Tweet [Industry News] Couplers Climb To 40 GHz Jack Browne | ED Online ID #22513 | March 18, 2010
A pair of high-performance directional couplers from Pulsar Microwave offers frequency coverage to 40 GHz with low loss and high directivity. Model CS20-52-436-9 is a 20-dB coupler that operates from 2 to 40 GHz with 1.6 dB insertion loss and more than 10 dB directivity. It maintains amplitude flatness of ±0.5 dB through 20 GHz and ±1.0 dB through 40 GHz. Rated for 20 W maximum power into a 1.20:1 VSWR load, the maximum VSWR is 1.80:1. Model CS20-53-436-13 is a 20-dB coupler with even wider frequency coverage of 1 to 40 GHz. It has insertion loss of 1.6 dB with directivity of better than 10 dB. The amplitude flatness is ±0.6 dB through 20 GHz and ±1.5 dB through 40 GHz. It can handle 20 W input power into a 1.20:1 VSWR load. Both couplers are supplied with female 2.92-mm connectors.
