Abstract :
Noise figures as low as 8 dB have been measured for Indium Phosphide reflection amplifiers operating over J-band (12-18 GHz). A single-stage, low noise, reflection amplifier circuit has been designed to provide a gain of 8 dB at 15 GHz., with a 1 GHz bandwidth. The effect of the package impedance parameters on available gain and bandwidth have been determined, and the properties of the completed amplifier are discussed.
