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
