The Keysight 83051A (formerly Agilent) is a high-performance, ultra-broadband microwave system preamplifier designed for systems designers and integrators. Operating from 45 MHz to 50 GHz, it provides a minimum of 23 dB gain and up to 16 mW (+12 dBm) of output power, making it ideal for recovering system losses and boosting available power in demanding RF and microwave automatic test equipment (ATE) systems. Its compact, modular form factor eliminates the need for multiple narrow-band amplifiers, simplifying system design and integration.
