Indium phosphide amplifier sets speed record

摘要

Redondo Beach, CA—Working as a team, engineers from TRW Electronic Space and Technology Div. and JPL Microwave (Pasadena, CA) recently fabricated and tested a low-noise amplifier chip that delivers 12.5-dB gain at 155 GHz. Described at the Indium Phosphide & Related Materials conference held in Massachusetts recently, the device is reportedly the highest frequency solid-state amplifier ever demonstrated.
