HFC10-26 – 10kW HF Directional Coupler

HFC10-26 – 10kW HF Directional Coupler

The HFC10 – 26 is a high-performance wide band directional coupler designed specifically for the HF frequency band. Utilizing advanced ferrite transformer techniques, this coupler achieves an incredibly compact and space-saving design, making it ideal for both permanent installations and field measurement applications.
With output samples of forward and reverse power flow, the HFC10 – 26 functions as an efficient “dual” coupler, ensuring that the reverse signal remains largely independent of the load on the forward port, and vice versa. Moreover, the coupler features built-in load resistors that effectively dissipate any unterminated coupled power, ensuring stable and reliable operation. Experience exceptional signal management and precision measurements with the HFC10 – 26 wide band directional coupler. Its compact form factor, high reliability, and accurate performance make it an indispensable tool for HF applications, providing valuable insights and seamless power flow control.
