The Keysight (Agilent) 83050A is an ultra-broadband microwave system amplifier designed for system designers and integrators. Operating over a very wide frequency band of 2 GHz to 50 GHz, it provides high gain and power boost capabilities to recover system losses and increase available power in RF and microwave automated test equipment (ATE) systems. By replacing multiple narrow-band amplifiers with a single unit, it simplifies setup complexity and eliminates the need for crossover networks or multiple bias power supplies.
