773D Coaxial Directional Coupler, 2 GHz to 18 GHz

The Keysight 773D is a high-performance directional coupler designed for broadband swept measurements in the 2 to 18 GHz range. This coupler is ideal for leveling broadband sources when used with an Keysight 8474B detector. The broadband design allows the use of a single test setup and calibration for tests spanning the entire 2 to 18 GHz range.
