The Narda 3002-20 is a directional coupler that samples and separates microwave energy without moving parts or adjustments. It enables accurate VSWR and attenuation measurements by isolating forward from reflected power, eliminating reflection errors in RF signal chains. With a fixed 20 dB coupling factor across 950 MHz to 2 GHz, this N-type connector module handles 500 W average power and 10 kW peak power, making it suitable for test benches, signal monitoring, and protective measurement applications.
