Guided Wave Technology's Coupling Matrix Synthesis (CMS) tool facilitates synthesis of N+2 coupling
matrices for Chebyshev bandpass filtering functions, with arbitrary finite-position transmission
zeroes.
The CMS tool
gives a fast and accurate overview of:
● Filter orders up to 12 ● Arbitrary placement of transmission
zeroes ● Complex transmission zeroes ● Extended parameter plotting
options ● S-parameter file (s2p) generation ● Topology matrix definition
of filter circuits ● Advanced graph and marker functions ● Easily
re-scalable axes ● Excellent overview - input/output together
● Saving and loading of designs ● Fast response ● Integrated manual
● Intuitive and very user friendly interface
