ABSTRACT:
A microwave filter is disposed on a substrate. The microwave filter is configured to connect a first microwave transmission line to a second microwave transmission line, configured such that a signal propagates from the first microwave transmission line to the second microwave transmission line. The microwave filter encompasses a highpass component of filter disposed in a symmetrical configuration with respect to a median plane placed perpendicular to the surface of the substrate, including the central axis of the first and second microwave transmission lines; and a lowpass component of filter connected parallel with the highpass component of filter, the lowpass component of filter being disposed in a symmetrical configuration with respect to the median plane.
