Directional Couplers

High Frequency Coaxial 10-16 dB, 0.5-40.0 GHz

Single directional couplers within this series operate from 500 MHz to 40 GHz and are available in standard values of 10, 13 and 16 dB. They fulfill narrow and broadband requirements with coupling tolerances of +/- 1 to 1.25 dB. These couplers are optimized for best matching and high directivity with flat coupling response.
