Agilent / Keysight 83050A Microwave System Amplifier, 2 GHz to 50 GHz

The Agilent/Keysight 83050A is a microwave system amplifier engineered for integration into automated test equipment and RF/microwave measurement systems. Operating across 2 GHz to 50 GHz, it delivers gain exceeding 21 dB across most of its bandwidth, with 30 dB typical performance in the 1–2 GHz band. The amplifier consolidates the function of multiple narrow-bandwidth units into a single platform, eliminating the need for complex crossover networks and reducing bias supply complexity.
