Model 3000-10 is a coaxial directional coupler from Narda, an L-3 Communications company, which provides 10-dB coupling from 225 MHz to 10 GHz. It can handle 200 W average power and 10 kW peak power, with the durability to handle both commercial and military applications. The directional coupler features insertion loss of 0.7 dB or less with directivity of at least 30 dB through 10 GHz. The maximum deviation from the nominal 10-dB coupling value is +/-1.2 dB with absolute calibration accuracy of +/-0.1 dB per 10-dB step. The coupler exhibits maximum VSWR of 1.15:1. It weighs 1.8 oz., measures 10.68 x 2.13 x 0.88 in., and uses Type-N female connectors.
