The WMHPDDC-10-300M-50DB-N dual directional coupler is a broadband RF sampling device covering 10 to 300 MHz, designed for high power signal monitoring, reflected power measurement, EMC testing, and laboratory applications requiring simultaneous forward and reverse power sampling. Utilizing a precision dielectric structure with carefully optimized coupling elements, the design delivers excellent directivity, low insertion loss, and highly stable performance across an ultra-wide operating bandwidth.

Engineered for demanding RF environments, the coupler maintains consistent electrical characteristics over temperature while supporting high average power handling. The mechanically robust construction and low loss mainline provide reliable operation for commercial, industrial, and test system integration where long-term stability and repeatability are critical.

The dual directional architecture provides independent forward and reverse coupled ports with nominal 50 dB coupling, enabling accurate monitoring of incident and reflected power without significantly loading the transmission line. The broadband design achieves excellent coupling flatness and impedance match over the full frequency range while preserving smooth frequency response and stable directivity characteristics.

Designed and manufactured using high quality RF materials and precision assembly techniques, the WBDC Series is ideal for HF, VHF, broadband amplifier systems, antenna measurement systems, communications infrastructure, EMC laboratories, and general-purpose RF monitoring applications.
