Agilent/Keysight 83441B Lightwave Source

The Agilent/Keysight 83441B is a broadband amplifier module for RF and microwave test and measurement applications requiring high gain and low noise amplification of weak signals. Operating across 10 MHz to 20 GHz, the module delivers approximately 10 dB gain with noise figure of 5 dB or lower, depending on revision and operating conditions. Its 50 Ohm nominal input/output impedance aligns with standard RF/microwave systems, while the compact form factor enables integration into diverse test configurations, laboratories, and field deployments.
