Agilent/Keysight 5086-7744

The Agilent/Keysight 5086-7744 is a Local Oscillator (LO) Distribution Amplifier Module engineered to amplify and distribute LO signals across a 3.0 GHz to 6.8 GHz frequency range. Designed for integration into spectrum analyzers and RF/microwave test systems, this module maintains signal integrity across multiple internal signal paths, including mixer and sampler outputs. The 5086-7744 serves as both a direct replacement component for existing Agilent/Keysight equipment and as a building block for new system designs requiring high-frequency signal distribution.
