The leader-mw LDC-0.5/6-30S 30dB Directional Coupler With 20db Directivity is a precision 30dB directional coupler designed for RF and microwave applications spanning 0.5 to 6 GHz. Engineered by Chengdu Leader Microwave Technology, this component is optimized for wideband signal monitoring and power sampling.
A key highlight is its 20dB directivity, which ensures excellent separation between forward and reflected waves, enabling accurate power measurements and efficient signal monitoring. The unit offers stable 30dB coupling, allowing minimal impact on the main transmission line while providing a precise sample of the signal. It supports a robust 30W power handling capacity, making it suitable for test systems, wireless infrastructure, and communication transceivers .
This coupler delivers a blend of high directivity, low insertion loss, and compact mechanical design, ensuring signal integrity in space-constrained environments. It is an ideal solution for applications requiring reliable power sensing and VSWR monitoring across a broad frequency range.
