The Narda 5292-02 is a precision broadband RF coupler that provides controlled signal sampling across 1.5–18 GHz with minimal insertion loss and exceptional directivity. This high-directivity coupler delivers 13 dB nominal coupling (±1 dB) and achieves 25 dB minimum directivity from 8–18 GHz, extending to 27 dB minimum below 8 GHz. It integrates into RF measurement chains, signal monitoring circuits, and test systems where accurate power extraction is essential.
