X-BAND SOLID-STATE DETECTOR/AMPLIFIER.
Abstract
Progress was made in the evaluation of several possible components and techniques that could be integrated into a miniaturized solid-state x-band detector amplifier. The major emphasis was placed on determining the pertinent characteristics of each component and evaluating its applicability to the program objectives. Two approaches to the design of a suitable mixer were evaluated. Measurements performed on a single-ended mixer employing a backward diode indicated that noise figures of about 9.0 db could be obtained with this technique. Additional circuit elements, a hybrid ring and an I.F. filter section, for use in a miniature strip transmission line mixer were completed and the electrical characteristics were encouraging. Attention in the area of I.F. pre-amplifiers was focused on the design, fabrication and test of an I.F. parametric amplifier circuit and evaluating solid-state pre-amplifier performance. An integrated receiver assembly consisting of a tunnel diode oscillator-mixer and a solid-state I.F. pre-amplifier was designed, fabricated and tested. This unit, which was constructed in a volume of 7 cubic inches (excluding connectors) exhibited an overall noise figure of 9.4 db.
