Abstract:

A five-stage, 100-Mc IF amplifier has been designed to improve short-range operation in a superheterodyne pulse radar system. Fast recovery time 0.3 microsec, or less for 30 dbm into the mixer and techniques for low-cost production were particularly emphasized in the design objectives. A relatively compact transistorized amplifier 5 cu in., packaged of straightforward design was realized, with a total gain variation of 5 db over a specified -55 to 75 C range. The performance indicated a suitable recovery time. Certain design considerations toward faster recovery time were rejected, however, on the basis that they would adversely affect some of the desired features such as voltage gain, simplicity of design, and production economy. A satisfactory automatic gain control AGC was incorporated in the design providing a 30-db increase in dynamic range. This report describes the design and performance of the IF amplifier. The design was determined feasible for the intended application. Author
