1kW HF Directional Coupler

The 1kW HF Directional Coupler is a wide band directional coupler for the HF band.

The coupler uses ferrite transformer techniques resulting in an extremely small compact device for permanent installation or for field measurement purposes.

Output samples of forward and reverse power flow are provided. Being effectively a “dual” coupler, the reverse signal is largely independent of the load on the forward port (and vice versa). Built-in load resistors dissipate any unterminated coupled power.

N.B. at 1kW the forward output signal is 1 Watt.

*The coupler is effective over a very much wider frequency range with a small degradation in performance. Calibration charts can be supplied for those out of band frequencies, where for example, measurement of harmonics is desired.
