HFC1-30 – 1kW HF Directional Coupler

HFC1-30 – 1kW HF Directional Coupler

The HFC1-30 is a wideband directional coupler designed for the HF frequency band, offering exceptional performance in a compact package. Utilizing cutting-edge ferrite transformer techniques, this coupler is optimized for permanent installations or field measurement purposes. With output samples of forward and reverse power flow, the HFC1-30 acts as an efficient “dual” coupler, providing accurate readings while maintaining independence between the reverse signal and load on the forward port. Additionally, built-in load resistors efficiently dissipate any unterminated coupled power, ensuring reliable operation. Economical and compact, the HFC1-30 is the ideal choice for those seeking a high-quality directional coupler that delivers excellent performance and versatility in HF applications. Enhance your signal management with this reliable and cost-effective device.
