Abstract
A three port diplex filter circuit with common, low, and high terminals having a frequency response up to 1 GHz comprises a Chebychev-like low pass filter connected between the common and low terminals and a Chebychev-like high pass filter connected between the common and high terminals, wherein each filter section further comprises a series resonant circuit connected between the low and high terminals, respectively, and ground. At lower crossover values, inductors are wound on powdered iron toroidal forms to counteract characteristic self resonance.
