Product Overview

The HP Agilent 779D is a Coaxial Dual Directional Coupler that is designed for swept measurements in the 1.7 to 12.4 GHz range. The HP Agilent 779D offers high directivity and mean coupling accuracy of plus or minus 0.5 dB which makes the HP 779D ideal for reflectometer applications. The auxiliary arms track very closely, making this coupler particularly useful for reflectometers driven by sweep oscillators such as the Agilent 8350B.
