Title :
Noise in Microwave Transmission Applications of Gunn and IMPATT Diodes -- The System/Circuit Interface in Gunn Diode Applications

Abstract :
Output power amplifiers using Impatt diodes are now being used in EM radio relay transmitters. In order to obtain high overall efficiency, the diodes are operated close to maximum rf output power. Since the noise figure increases monotonically with output power, an optimum tradeoff between power and noise must be sought.
