"Microwave and RF Linear Simulation CAE Package for WindowsTM",
Microwave Journal, May 1993.
Computer-aided engineering (CAE) for microwave and RF linear simulation has taken a major step forward with the introduction of MMICADTM for Windows Version 1.0. Building upon the success of MMICAD 5.0 for DOS, this software has been ported to the popular Windows 3.1 operating system. The software is not a mere translation, but is a complete revision of the code that takes advantage of the memory and multitasking capabilities of the Windows operating system. For example, MMICAD for Windows can now analyze circuits of unlimited complexity with up to 20 ports and 8192 frequency of parameter points.

"Software Designs Varactor Diodes",
Microwave Journal, April 1992.
MMICAD's parameter sweep function opens new possibilities for RF and microwave design engineers in designing a varactor diode with linear tuning characteristics. The linearity of voltage-controlled oscillators is dictated by the varactor diode tuning characteristic. In the past, this parameter was not within the control of the design engineer, which meant working around whatever tuning curve was the closest to the desired depth. With MMICAD it is now possible to specify a C-V specification for a varactor tuning diode that will produce optimum results. Different C-V profiles for this new varactor then can be used in MMICAD's simulation of a complete oscillator circuit to describe the total frequency vs. voltage-tuning characteristics accurately.

Microwave Journal, August 1990.
Monolithic Microwave Integrated Circuit Analysis and Design software (MMICAD) is a general purpose linear analysis and optimization program for both active and passive electronic circuits. The program features a menu-driven windowed environment. Single keystroke on-line context sensitive help is available throughout the program. Both circuit files and graphics can be imported to a desktop publishing program. MMICAD comes complete with a circuit file editor that includes cut-and-paste and search-and-replace options. The comprehensive error checking characteristic identifies the error in simple language and invokes the editor at the line number of the problem.
