The object of this program is to develope and evaluate tunnel diodes and point contact diodes for use as mixers at 3.2 millimeters. Preliminary results are presented on a galliumarsenide, phosphor bronze whisker point contact diode mixer having a high IF output 2 - 4 Gc. Background evidence, as well as current measurements, are presented which show the advantages gained by using a high IF as compared to a low IF less than 100 Mc. Poor performance of movable waveguide contacting shorts has initiated the fabrication of electro-formed waveguide. A low impedance variable pulse width-amplitude circuit has been developed for pulse bonding tunnel diode junctions. Several materials are considered for tunnel diodes. Author
