The Keysight 775D is an economical dual-directional coupler designed for swept measurements in the 450 to 940 MHz range. Its high directivity and mean coupling accuracy of plus or minus 0.5 dB makes the Keysight 775D ideal for reflectometer applications. The auxiliary arms track very closely, making this coupler particularly useful for reflectometers driven by sweep oscillators.
