AppCAD Version 4.0.0
This is the current, released version of AppCAD
(previous version was Agilent-branded v3.02)
What is New in version 4.0.0?
1. AppCAD's developer is now part of , subsequently AppCAD has been re-branded from Agilent Technologies to Avago Technologies
2. Windows 7/8 compatibility
3. Circuit Design & Everything
S-Parameters
Maximum number of files increased from 3 to 6
&Auto-set Freqs From File& & This checkbox option
sets Start-Stop-Step frequencies from the last file loaded. Assumes linear
frequency sweep. If a file has a mixed Sweep Plan, all data points are loaded
without loss of precision, however the Step frequency is set to last increment
of the file.
Rectangular Plot & two new features:
Option to manually set Y-Axis min/max in
addition to auto-scale
&Offset (dB)& & Applies to |S21| and |S12|.
Useful to account for gain/loss offsets, e.g., PCB or text fixture loss. The
Offset value is added algebraically to the plot.
Two new calculation parameters:
&Cascade Analysis& & applies to |S21| in dB.
Plots sum of |S21| for all files checked.
|S11| and |S22| added to &Match& category. These
are the parameters commonly referred to as &Return Loss& within the RF
industry. See &Return Loss & A note on definition and usage& in Help [F1] under
&Parameter Definitions&
&Set up plot area& & Clicking this button
displays several new plot options for formatting the plotting area
Choice of rectangular plot area color scheme
Solid color
Vertical or horizontal color gradient
Picture background (must be in BMP format at this
Choice of grid color
Multi-parameter plotting. No longer restricted to plotting parameters onl e.g., can now plot Gt, VSWR, and Phase on same graph.
Fixed Group Delay glitch that could occur in
transitions between &180&
4. Circuit Design & Balun
Added solution for 4-element balun
&Balun Tutorial& in Help [F1] has been expanded to
include derivation of 4-element balun from 6-element prototype
Moved from Balun from &Passive Circuits& to
&Circuit Design& menu category
5. Transmission Lines & Microstrip,
Coplanar, and Coax
Added calculation for Electrical Length as Air
Line equivalent
Added calculation for Delay time
Known Issues:
Norton (Symantec) false positive. When attempting to
download & install from , Norton 360 (antivirus software)
removes the installation program from the download and says it contains the
WS.Reputation.1 virus. This does not mean Norton has detected a virus. Norton
uses an internal &reputation based& data base of programs as part of
their virus protection scheme, and if it encounters a program unknown to Norton,
it summarily quarantines it, even if it is not a virus.

Everything S-Parameters
Everything S-parameters is the quick and easy way of analyzing S-parameter
data for devices or circuits to obtain key performance parameters such as gain, stability,
reflection loss, and matching impedances.
A unique feature of AppCAD's Everything S-Parameters
is the ability to load up to 3 sets of SnP files and make side-by-side comparisons.
This side-by-side comparison feature is exceptionally useful for comparing different
devices to assist with design-in decisions, or analyzing the same device under different
conditions, e.g., three different bias currents or temperatures. This feature is also
useful for looking at circuit performance before and after design changes.&
Also unique to AppCAD's Everything S-Parameters is the 2-Port
Single-ended to 1-Port Differential Impedance conversion. This function converts of
a set of conventional, 2-port, single-ended S-parameters into a 1-port differential
impedance. This feature is very useful for measuring balanced circuits with a standard
vector network analyzer.
Everything S-parameters can analyze over 40 different parameters covering:
<font color="#-Port Single-ended to 1-Port Differential Impedance conversion
Gain (five different gains)
Stability analysis (u1, u2, K)
Matching impedances (gain and NF)
Return Loss, VSWR
Gain Variation (including min/max, average, and mid-band gains)
Isolation (reverse gain)
Phase Linearity, Group Delay
Noise Figure
Gain, stability, and NF circles
... and more
Calculated results may be displayed in these formats:
Tabular listing of numeric results
Rectangular plot vs. Frequency
Smith chart vs. Frequency

&Commentary on Stability& ... potential instability of active devices or
circuits and what to do about it.
A description of calculating a 1-Port Differential Impedance from
a set of 2-Port Single-ended S-parameters.
A library of S-parameters for many of Agilent's new products is also installed.

What is AppCAD?
AppCAD is an easy-to-use program that
provides you with a unique suite of RF design tools and computerized Application Notes to
make your wireless design job faster and easier. AppCAD's unique, interactive
approach makes engineering calculations quick and easy for many RF, microwave, and
wireless applications. AppCAD is useful for the design and analysis of many
circuits, signals, and systems using products from discrete transistors and diodes to
Silicon and GaAs integrated circuits. The keyword for AppCAD is easy
- no circuit files, no manuals - just quick and easy.
AppCAD is updated with new
features as time permits. This web site will always have the latest downloads
and version information.
The AppCAD Story
The Application Engineering staff of the
Microwave Semiconductor Division of Hewlett-Packard created AppCAD as a design
help for RF & Microwave (a.k.a., wireless) designers. AppCAD was then,
and still is, distributed free of charge as a service to the wireless engineering
community.
AppCAD was originally released in 1990
by Hewlett-Packard as
version 1.02 (the &Classic& version). Version 1.02 was a DOS program that was
compatible with Windows 3.x. Although based on the original MS-DOS(R) version
of RF and Microwave AppCAD &Classic,& the current version of AppCAD runs on 32-bit Windows(R) operating systems and contains many
new and innovative design programs.
In 1999, Hewlett-Packard split into
two companies, with the computer-related business retaining the
Hewlett-Packard name ($49 billion revenue, 88,500 employees) and the test,
measurement, semiconductor, and chemical analysis business sectors becoming
Agilent Technologies ($11 billion revenue, 47,000 employees). At this time,
the Microwave Semiconductor Division of HP become the Wireless Semiconductor
Division of Agilent Technologies, which retained the AppCAD program.
In 2005, Agilent spun its semiconductor
sector, including the Wireless
Semiconductor Division, off into a new
company named Avago Technologies
($4 billion revenue, 8,500 employees).
AppCAD Classic
The DOS version of AppCAD
still contains
useful legacy calculations and is
available for download, however it is no longer
supported.
Partial Contents of original AppCAD
Classic (DOS version):
Two-port Analysis
Thermal Design
PIN Switch Design
Mixer Spurious Search*
Transmission Lines*,
Cascade Noise Analysis*

* Now included.in the Windows version.
Note that AppCAD Classic only runs on
&real& DOS. With the exception of the DOS emulator packaged with Windows XP, the
other Windows emulators lack the true DOS functionality required by AppCAD and will
only run parts of the program.

on this Site is provided in good faith for general informational purposes
only. This Site may contain information submitted by a third parties.&
This information should not be relied upon for any specific purpose and no
representation or warranty is given as to its accuracy or completeness.The Setup program accepts optional command line parameters. These can be useful to system administrators, and to other programs calling the Setup program.
Shows a summary of this information. Ignored if the UseSetupLdr [Setup] section directive was set to no.
Disables the This will install... Do you wish to continue? prompt at the beginning of Setup. Of course, this will have no effect if the DisableStartupPrompt [Setup] section directive was set to yes.
Instructs Setup to be silent or very silent. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. When a setup is very silent this installation progress window is not displayed. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with DisableStartupPrompt or the '/SP-' command line option explained above).
If a restart is necessary and the '/NORESTART' command isn't used (see below) and Setup is silent, it will display a Reboot now? message box. If it's very silent it will reboot without asking.
Instructs Setup to suppress message boxes. Only has an effect when combined with '/SILENT' or '/VERYSILENT'.
The default response in situations where there's a choice is:
Yes in a 'Keep newer file?' situation.
No in a 'File exists, confirm overwrite.' situation.
Abort in Abort/Retry situations.
Cancel in Retry/Cancel situations.
Yes (=continue) in a DiskSpaceWarning/DirExists/DirDoesntExist/NoUninstallWarning/ExitSetupMessage/ConfirmUninstall situation.
Yes (=restart) in a FinishedRestartMessage/UninstalledAndNeedsRestart situation.
5 message boxes are not suppressible:
The About Setup message box.
The Exit Setup? message box.
The FileNotInDir2 message box displayed when Setup requires a new disk to be inserted and the disk was not found.
Any (error) message box displayed before Setup (or Uninstall) could read the command line parameters.
Any message box displayed by [Code] support function MsgBox.
Causes Setup to create a log file in the user's TEMP directory detailing file installation and [Run] actions taken during the installation process. This can be a helpful debugging aid. For example, if you suspect a file isn't being replaced when you believe it should be (or vice versa), the log file will tell you if the file was really skipped, and why.
The log file is created with a unique name based on the current date. (It will not overwrite or append to existing files.)
The information contained in the log file is technical in nature and therefore not intended to be understandable by end users. Nor is it designed to be machine- the format of the file is subject to change without notice.
"filename"
Same as /LOG, except it allows you to specify a fixed path/filename to use for the log file. If a file with the specified name already exists it will be overwritten. If the file cannot be created, Setup will abort with an error message.
Prevents the user from cancelling during the installation process, by disabling the Cancel button and ignoring clicks on the close button. Useful along with '/SILENT' or '/VERYSILENT'.
Prevents Setup from restarting the system following a successful installation, or after a Preparing to Install failure that requests a restart. Typically used along with /SILENT or /VERYSILENT.
Specifies a custom exit code that Setup is to return when the system needs to be restarted following a successful installation. (By default, 0 is returned in this case.) Typically used along with /NORESTART. See also:
Instructs Setup to close applications using files that need to be updated by Setup if possible.
Prevents Setup from closing applications using files that need to be updated by Setup. If /CLOSEAPPLICATIONS was also used, this command line parameter is ignored.
Instructs Setup to restart applications if possible. If Setup didn't close these applications (for example because /NOCLOSEAPPLICATIONS was used), this command line parameter is ignored.
Prevents Setup from restarting applications. If /RESTARTAPPLICATIONS was also used, this command line parameter is ignored.
"filename"
Instructs Setup to load the settings from the specified file after having checked the command line. This file can be prepared using the '/SAVEINF=' command as explained below.
Don't forget to use quotes if the filename contains spaces.
"filename"
Instructs Setup to save installation settings to the specified file.
Don't forget to use quotes if the filename contains spaces.
Specifies the language to use. language specifies the internal name of the language as specified in a [Languages] section entry.
When a valid /LANG parameter is used, the Select Language dialog will be suppressed.
"x:\dirname"
Overrides the default directory name displayed on the Select Destination Location wizard page. A fully qualified pathname must be specified. May include an "expand:" prefix which instructs Setup to expand any constants in the name. For example: '/DIR=expand:{pf}\My Program'.
"folder name"
Overrides the default folder name displayed on the Select Start Menu Folder wizard page. May include an "expand:" prefix, see '/DIR='. If the [Setup] section directive DisableProgramGroupPage was set to yes, this command line parameter is ignored.
Instructs Setup to initially check the Don't create a Start Menu folder check box on the Select Start Menu Folder wizard page.
Overrides the default .
If the specified type exists and isn't a custom type, then any /COMPONENTS parameter will be ignored.
"comma separated list of component names"
Overrides the default
settings. Using this command line parameter causes Setup to automatically select a custom type. If no custom type is defined, this parameter is ignored.
Only the specified compone the rest will be deselected.
If a component name is prefixed with a "*" character, any child components will be selected as well (except for those that include the dontinheritcheck flag). If a component name is prefixed with a "!" character, the component will be deselected.
This parameter does not change the state of components that include the fixed flag.
Deselect all components, then select the "help" and "plugins" components:
/COMPONENTS="help,plugins"
Deselect all components, then select a parent component and all of its children with the exception of one:
/COMPONENTS="*parent,!parent\child"
"comma separated list of task names"
Specifies a list of
that should be initially selected.
Only the specified ta the rest will be deselected. Use the /MERGETASKS parameter instead if you want to keep the default set of tasks and only select/deselect some of them.
If a task name is prefixed with a "*" character, any child tasks will be selected as well (except for those that include the dontinheritcheck flag). If a task name is prefixed with a "!" character, the task will be deselected.
Deselect all tasks, then select the "desktopicon" and "fileassoc" tasks:
/TASKS="desktopicon,fileassoc"
Deselect all tasks, then select a parent task and all of its children with the exception of one:
/TASKS="*parent,!parent\child"
"comma separated list of task names"
Like the /TASKS parameter, except the specified tasks will be merged with the set of tasks that would have otherwise been selected by default.
is set to yes, the specified tasks will be selected/deselected after any previous tasks are restored.
Keep the default set of selected tasks, but additionally select the "desktopicon" and "fileassoc" tasks:
/MERGETASKS="desktopicon,fileassoc"
Keep the default set of selected tasks, but deselect the "desktopicon" task:
/MERGETASKS="!desktopicon"
Specifies the password to use. If the [Setup] section directive Password was not set, this command line parameter is ignored.
When an invalid password is specified, this command line parameter is also ignored.winqsb求解非线性方程为什么我求解的时候，每次在solve the problem 之后的solution setup每次设置那些什么 stopping tolerance ,starting penalty parameter ,penalty mutiplier 设置不同数目竟然结果相差非常之大，_百度作业帮
