HP 772D Coaxial Dual-Directional Coupler, 2 GHz to 18 GHz

Product Summary

The HP 772D is a high-performance, dual-directional coupler designed for broadband swept measurements in the 2 to 18 GHz range. This coupler can be combined with HP power sensors and power meters (such as the HP 438A dual power meter) for reflectometer applications. Forward and reverse power measurements on transmitters, components, or other broadband systems are made simpler using the HP 772D. The broadband design allows the use of a single test setup and calibration for tests spanning the entire 2 to 18 GHz range.

Product Features

• Wide frequency coverage simplifies testing

• High directivity

• Ideal for reflectometer measurements
