Millimeter wave front end

摘要

A system and method providing millimeter wave front end circuitry utilizing waveguide E-plane bandpass filters for both out of band frequency rejection as well as reverse and spurious propagation of in band signals. Accordingly, a conductive base plate is formed having various waveguides. Circuit boards of the front end circuitry are disposed in ones of the waveguides which reject in band frequencies in order to prevent undesired coupling of signals. Additionally, waveguides rejecting out of band frequencies are coupled to the circuit boards in order to provide bandpass filters utilized by the front end circuitry.
