The Narda 3292-1 is a broadband directional coupler engineered for precise RF and microwave signal monitoring and control across 1 to 18 GHz. It delivers 13 dB nominal coupling with ±1 dB variation and maintains directivity of 25 to 27 dB (1–8 GHz), enabling accurate signal extraction and power measurement without disrupting primary signal paths. Maximum insertion loss of 1 dB preserves system efficiency while supporting average power handling of 5 W and peak impulse ratings to 100 kW.
