1. In a monopulse receiver operating in the 94 GHz band and higher bands, a first detector comprising:
- (a) a first, a second, a third and a fourth balanced detector clustered about a central point on a common substrate, each one of such detectors including a pair of similarly poled beam-lead diodes;
(b) means for optically coupling, via the beam leads of each such diode, radio frequency signals to be detected;
(c) means for optically coupling first local oscillator signals to each pair of beam-lead diodes; and
(d) an output line electrically connected to a junction between each pair of beam-lead diodes.

Abstract
A pulse radar for operation at 94 GHz and higher frequencies is shown to include an antenna, a diplexer and first detector that are each optically fed so that radio frequency signals may be, when transmitting, passed through the diplexer to the antenna and, when receiving, from the antenna through the diplexer to the first detector.
