RF Directional Couplers

Broadband RF directional couplers are a common component in radiated immunity test systems. By placing a directional coupler between your RF amplifier and antenna/probe you can use an RF power sesnor to monitor the amount of power throughput and verify the measurements from your current monitor/sensing probe and spectrum analyzer are accurate.
