Harmonic Generation, Mixing and Detection of Millimeter and Submillimeter Waves Using Parametric or Tunnel Diodes

A general discussion of harmonic generation, mixing and detection through use of parametric or tunnel diodes is given. The efficiency, noise factor and sensitivity of such devices are presented. In particular, the circuit design and its associated diode fabrication, together with recent experimental results at millimeter wave frequencies are described. Based on be general considerations, similar experimental results can be anticipated in the submillimeter wave region.
