Precision RF Couplers for Efficient Signal Monitoring and Management

Precision directional couplers engineered for accurate signal sampling with minimal insertion loss.

Hughes RF couplers extract a proportional signal sample from the main transmission path whilst allowing primary signal flow to continue with minimal attenuation and maintained impedance characteristics. Available in both hybrid and AIR dielectric constructions, these directional sampling devices deliver high directivity, excellent port-to-port isolation, and controlled coupling factors essential for accurate power monitoring and system measurement without disrupting RF transmission. AIR dielectric couplers provide enhanced passive intermodulation performance and superior thermal stability, making them particularly suited to high-power macro cell installations where low-interference operation is critical. The precision design maintains consistent coupling accuracy across wide operating bandwidths and power levels, enabling reliable signal monitoring in distributed antenna systems, base station infrastructure, and test equipment applications. Available with various coupling values, frequency ranges, and connector configurations, Hughes couplers support system monitoring, feedback control, and signal analysis requirements across telecommunications networks where non-intrusive signal access is essential for performance verification and network optimisation.
