Oct. 14, 2010

Model 3000-10 is a coaxial directional coupler from Narda, an L-3 Communications company, designed for 10-dB coupling from 225 MHz to 10 GHz. It features directivity of at least 30 dB and insertion loss of 0.7 dB or less. It can handle 200 W average power and 10 kW peak power. The coupler has maximum deviation from nominal coupling of +/-1.2 dB and absolute calibration accuracy of +/-0.1 dB per 10-dB step. It exhibits maximum VSWR of 1.15:1 and measures 10.68 x 2.13 x 0.88 in. with Type N female connectors. It is ruggedized for both commercial and military applications.
