Abstract:

This report includes Lenkurt Electric Co., San Carlos, Calif. HIGH FREQUENCY TRANSISTOR STUDY. Letter progress and Interim engineering rept. 1 July-30 Sep 61. 20 Oct 61, 8p. incl. illus. Subcontract to Hughes Aircraft Co., Newport Beach, Calif., Contract NObsr-85296A down-converter circuit was developed in which the pump source is obtained by using the transistor in transit-time mode while parametric mixing occurs with mixing gain resulting from a egative conductance pro uced by the pump frequency. No external feedback is required between the tuned collector and emitter circuits. Using transistor structures in the conventional TO-5 package, a 50 db power conversion gain was obtained with a sensitivity of 1 microvolt and reasonable signalto-noise ratios. This conversion gain is 15 - 20 db higher than optimum gain for a conventional transistor mixer. Author
