722N Dual Directional Coupler Series are high power capable with extremely low insertion loss and are ideal for your systems applications where precise monitoring, external leveling, signal mixing or swept transmission and reflection measurements are desired. Coupled ports are DC isolated and will only pass RF. Nominal coupling values of 10, 20, 30 and 40 dB are available.
