The HFC30-26 is a wide band directional coupler for the HF frequency 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.
