Multi-Band Frequency Converter.

Abstract

The report describes work on a sensitive superheterodyne frequency downconverter to convert six channels in the 18-42 GHz range to the 4-8 GHz range. Accomplishments include: The design and fabrication of 26, 30, and 34 GHz Gunn diode oscillators providing +14 dBm output power; The design of broadly frequency selective channel dropping couplers which can be fabricated in dielectric image guide; The design and fabrication of Schottky-Barrier diode mixer mount with a 6-8 dB conversion loss over the 18-22 GHz band. The design and fabrication of an integrated mixer assembly in metal waveguide which includes both waffle iron and waveguide-below-cutoff filters, a 10 dB LO post-type coupler, and a single ended diode mixer; The design and fabrication of a coax to image guide mode converter (launcher); The evaluation of thin film attenuators to be used with image guide.
