Description

A specialized type of directional coupler used to sample or extract a portion of the signal from a transmission line, typically featuring multiple coupling ports. This design improves coupling accuracy, enhances power handling capacity, and offers better performance over a wide frequency range. Multi-hole directional couplers are ideal for applications requiring precise power measurement, signal monitoring, or feedback in high-performance systems like radar, wireless communication, and RF testing, providing low insertion loss, high isolation, and excellent directional sensitivity.
