ABSTRACT:
An electrical filter network particularly suitable for use at microwave frequencies, comprises a main transmission path and a plurality of pairs of secondary paths interconnected by couplers which divide an incoming signal into components on the several paths and recombine the transmitted components to provide an output signal. Conditions are placed on the electrical lengths of the transmission paths; the magnitude of the frequency-independent components of phase change along the paths and the wave amplitudes in the paths.
