RF Cafe Forums, I am doing R & D development work
on some projects and need the following ---

What do any of you have or know about in software that would take any combination of passive circuit elements such as R L C (in any combinations - series/parallel etc.) including several BALANCED transmission lines of any length & Zo (lossy and lossless) connected in various combinations to produce a desired effect over RF frequency ranges. Basically - the immediate circuit project requires a desired input impedance characteristics and with careful planning ball park - try the potential circuit in a computer software simulation mode
to see if the component selections are working as desired.

If the software exists - I would assume that it would be able to calculate
the currents/voltages/phase at any node in the complex circuit with a given voltage input to the circuit.

Hello,
Try Agilent ADS, I think it will do the job.

regards

ADS is fine if you have $80K laying around. If the circuits are not larger than 25 components , then ANSOFT Serenade student version is free and will also, do the job. If the project will not last more than 30 days, then Microwave Office will allow you to evaluate a full version for free. Finally, Eagleware, Genesis is ~4K, but they have another version that will do the job for you that is 1K. ADS, for now is the leader, but they are quickly loosing ground to Microwace Office in the IC platforms and Eagleware in the RF platforms.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
