Description :

The Keysight 778D is an economical dual-directional coupler designed for swept measurements in the 100 MHz to 2 GHz range. Its high directivity and mean coupling accuracy of ±0.5 dB makes the Keysight 778D ideal for reflectometre applications. The auxiliary arms track very closely, making this coupler particularly useful for reflectometres driven by sweep oscillators.
