Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: RF Input Impedance Software
postPosted: Mon Mar 28, 2005 6:58 pm
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.

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

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.
