The Keysight 774D is an economical dual-directional coupler designed for swept measurements in the 215 MHz to 450 MHz range. Its high directivity and mean coupling accuracy of plus or minus 0.5 dB makes the Keysight 774D ideal for reflectometer applications. The auxiliary arms track very closely, making this coupler particularly useful for reflectometers driven by sweep oscillators such as the Keysight 8350B.
