- I have colleagues working on Microwave Oscillators that reported some
- difficulties working with PSpice, mainly when the Q factor of the
- resonant element is too high (some thousands).
-
- However, there is a kind of simulation software designed to achieve,
- quickly and precisely, the forced response of nonlinear oscillator
- circuits, using techniques known as "Harmonic Balance Techniques" that
- can handle oscillators, power amplifiers, frequency multipliers, etc.
-
- I've worked in Microwave frequency doublers using a software called
- "Microwave HARMONICA" with very good results but only once in a Master
- Degree work. People from Microwaves Group at my University are using
- also a system from HP known as "Microwave Design System-MDS". I think
- that the company that sells TOUCHSTONE has also some software for that
- kinf of problems.
-
- Some months ago, in IEEE SPECTRUM, appeared a broad description of
- many CAD Software for Electronics with the companys address given.
-
- BY THE WAY I HAVE NOT COMERCIAL RELATIONS WITH ANY OF THE COMPANIES
- THAT SELL THE ABOVE MENTIONED SOFTWARE.
-
- Hope this helps...
