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.
