RF Directional Couplers

An RF directional coupler allows a portion of an RF signal to be sampled or monitored without disrupting the main transmission line. Engineers use directional couplers for signal measurement and power level tracking in systems like antennas and transmitters. These components offer high isolation and low insertion loss across frequency ranges. Applications include lab testing and live communication systems.
