Abstract :
Describes a new application of monolithic microwave integrated circuits (MMICs), summing and difference amplifiers, and their integration into a microwave monolithic monopulse comparator for use in monopulse radars. A GaAs monolithic monopulse comparator operating at L-band has been developed. The complete circuit was composed of four summing amplifiers and four difference amplifiers. The circuit had a gain of 8.5 dB and null depths of approximately 25 dB to 30 dB, and it was biased from a single positive supply.<>
