EMAIL TO: kgfaison@aol.com FaiSyn Automatic Filter Synthesizer For Windows 1.0 INTRODUCTION: FAISYN is a low cost, effective alternative to expensive commer- cial filter synthesis packages. The program has been used successfully to design countless lumped element filters and diplexers from 10's of KHz to 1.5GHz and is the result of many years experience in filter design. Many designers know that filter design is often an iterative process. In the old days a lot of tedious number grinding was required to arrive at an optimal solution. FAISYN eases the burden by allowing the designer to quickly synthesize and simulate a variety of circuits. These circuits may also be exported and simulated on one of the popular commercial circuit simulators (FAISYN currently supports PSPICE-TM Microsim, MMICAD-TM Optotek and TOUCHSTONE- TM HP/EESOF circuit formats). NOTE: An evaluation version of PSPICE capable of running FAISYN filter circuits is available at very low cost from Microsim Corp or for free from the EDN magazine BBS. 1.1 INSTALLATION: 1) Create the directory C:\FAISYN on your hard drive. 2) Copy the files from floppy to C:\FAISYN, unzip if necessary. 3) Under the Windows Program Manager: -Select File-New-Program, click OK -Type C:\FAISYN\FAISYN.EXE in the command line box. -Type C:\FAISYN in the working directory box, click OK. -Faisyn is now installed in the current active Program Group (ie, Main, Accessories, etc). Alternatively, the program my be started by selecting File-Run in Program Manager and typing c:\faisyn\faisyn.exe in the Command Line Box. 1.2 RUNNING FAISYN FOR THE FIRST TIME: FAISYN uses modern filter design theory to compute lumped element low, high and bandpass filters. All filters are based on normalized low pass prototypes. The design and simulation process takes place in two seperate windows. The "General Filter Design Window" is where the user inputs the desired design parameters such as source and load resistances and filter order N. The filter type (Butterworth, Chebyshev, etc), transformation (Low Pass,High Pass, Band Pass, etc) and circuit file format (MMICAD, PSPICE or TOUCHSTONE) are also selected in this window. After all the parameters have been set the user selects the synthesize button to calculate and display the network. The program may prompt youfor additional information during this process depending upon the design parameters chosen. You may respecify and synthesize the network as many times as you like. When a suitable design has been found you may choose the simulate button to open the "Network Analyzer" window. Select the sweep button to see the response of your network. The default settings will display the magnitude of S21 and S11 of your network in dB format. You may choose a variety of other display variables and plot formats by setting the corresponding controls. You may zoom in to a particulate portion of the plot by adjusting the scaling on the horizontal and vertical axis. The plot title may be changed by selecting "Options". Select "Print" to get a hardcopy of your simulation plot. You may want to set your printer to landscape mode for best results. When you finish your simulation select "Close" to return to the "General Filter Design Window". There are several options that have not been completed in this release of the program. These include the "USER DEFINED" and "ELLIPTIC" filter responses and Smith Chart plot capability. Although displayed, they cannot be selected by the user. 2.0 REGISTRATION: There are many enhancements planned for the program, however the rate at which these will be implemented will depend on the response from the user community. FAISYN is SHAREWARE and is not free. The beauty of shareware is that it allows the user to try the software for a period of time to determine if it is truly useful before paying for it. Registering the product gives me motivation to make improvements and allows me to cover some of the costs involved (software, books & hardware, etc). So try it for thirty days and let your conscience be your guide! For those of you without a conscience (just kidding!) I have add- itional incentives including a set of filter application notes and at least one free (probably more...) update to a future revision of FAISYN. 2.1 "IN THE WORKS": Another product FAISYN-MATCH is also "in the works". FAISYN-MATCH aids in the design of broad band impedance matching networks and has been used to design state of the art high dynamic range RF and Microwave amplifiers. These are real world production designs, both discrete and monolithic. Again, registered users will be notified when this product is released. Comments and suggestions for future releases are welcome and greatly appreciated. Kevin Faison Carriage House Engineering EMAIL: kgfaison@aol.com 2.2 Updates in this release The current version of FaiSyn Automatic Filter Synthesizer is 2.1 The following improvements and/or fixes have been incorporated in this release. -Version 2.0 1) Added distributed parallel line coupled filters. 2) Added distributed stepped impedance resonator filters. 3) Added additional design hints. 4) Added solid & dashed lines for hard copy plots. 5) Fixed option buttons to reflect their availability during design & simulation. 6) Resized many of the design windows to prevent clipping on low resolution systems. 7) Added EMAIL address to the author (still evaluating my present provider, address could still change. Snail mail is still OK). -Version 2.1 1) Fixed spice file format in HP filters. 2) Added Top-C coupled band pass filter. 3.0 License Agreement ----------------- The use of FAISYN is subject to the following terms and condi- tions.
