Dual Directional Couplers

Broadband Coaxial SMA and 2.92mm, to 40 GHz

Dual directional couplers from Pulsar Microwave are available in standard values of 10, 20 and 30 dB with coupling tolerance of +/- 1.25 dB. They are available in narrowband and wideband designs from 500 MHz to 40 GHz. Most models have a coupling flatness of +/- 0.8 dB. Input Power is rated for 50 watts.
