MICROWAVE ACOUSTIC DELAY LINE AND RELATED ACTIVE DEVICES.

Abstract

Primarily experimental efforts during this period have produced 60 Mc CdS amplifiers with 40 db net electrical gain and 120 db/cm gain values, with power output levels of 20 mw. Broadband, 60 Mc, diffused surface-transducers in CdS have been made with less than 12 db losses, and quartz transducer looses at 60 Mc have been reduced below 3 db. Electrically tunable millihenry inductances with Q greater than 10 and Hall effect, non-reciprocal negative resistance circuits operating over a 30:1 frequency range are described along with methods for achieving low temperature ohmic contacts to CdS crystals. These results represent major progress toward the objective of complex functional electronic circuits in single crystal structures without discrete elements or interconnections. (Author)
