1. A transition for coupling a horn antenna to a matched diode detector comprising:

  • a. a ridged waveguide operatively coupled to the horn antenna;

    b. a substrate for supporting a diode chip, carrying said matched diode detector, adjacent said waveguide, the substrate also supporting a pair of RF pick-up probes, each RF probe having a portion which is coupled with the diode detector chip, the substrate also supporting conductors coupled to said diode chip and to said pair of RF pick-up probes; and

    c. a waveguide short circuit at least partially enclosing the diode chip and disposed adjacent said substrate.
