Filter and Coupling Matrix
Synthesis Software. Get an overview of main filter parameters
in seconds, without complex circuit models and modeling.
Our Coupling Matrix Synthesis™ software facilitates synthesis
of N+2 coupling matrices for Chebyshev bandpass filtering
functions, with arbitrary finite-position transmission zeroes.
The software also facilitates coupling matrix synthesis
through topology matrix definition. It gives a fast and
accurate overview of insertion loss, isolation, group delay
and coupling coefficients versus filter order, return loss
and transmission zero positions. The software allows placement
of complex transmission zeroes, which opens up for group
delay shaping and analysis.
