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.
