Agilent / HP 774D
Coupler
Description
The Agilent 774D is an economical dual-directional coupler. This coupler was designed for swept measurements in the 215 MHz to 450 MHz range. Its high directivity and coupling accuracy of plus or minus 0.5 dB makes the 774D perfect for reflectometer applications. The auxiliary arms track very closely, which makes this coupler very useful for reflectometers driven by sweep oscillators. One would be the Agilent 8350B.
