Agilent / HEWLWTT PACKARD HP 777D Dual-directional Coupler

The Agilent 777D is an economical dual-directional coupler designed for swept measurements in the 1.9 to 4.0 GHz range. Its high directivity and mean coupling accuracy of plus or minus 0.5 dB makes the Agilent 777D ideal for reflectometer applications. The auxiliary arms track very closely, making this coupler particularly useful for reflectometers driven by sweep oscillators.
