Abstract
A limited-bandwidth microwave transversal or recursive filter, compatible with microwave monolithic integrated circuit (MMIC) design requirements is described in this invention. The device comprises a means to split an incident signal into multiple parts for distribution among a plurality of input ports of frequency-selective feedforward and feedback network branches comprising filter elements and active devices so designed as to provide a desired degree and type of signal filtration. After filtration, the resulting signals from these branches are combined to form a composite filter output signal.
