WIDEBAND AMPLIFIER USING BTL M2107 MICROWAVE TRANSISTOR
Abstract
An evaluation was made of the M2107 microwave transistors (first models) AS WIDEBAND AMPLIFIERS. The transistor unit, bias supply, and test circuits are de cribed. Presented in graph form are power gain and noise figure measurements as a function of frequency. The M2107 is a diffused base PNP germanium transistor, with a mesa structure, designed for use as an amplifier at 3000 mc. Techniques have been refi ed to permit accur te fabrication wi h small dimensions, and the unit has been encapsulated in a coaxial package. The M2107 microwave transistor operated as an untuned, wideband amplifier (i.e., amplification of electrical signals at frequencies from zero to 1000 mc). The first available transistor models di not permit useful operation at the design frequencies; however, they were capable of useful application. (Author)
