High-power broadband bidirectional coupler (100K - 1000MHz 100W)

This dual directional coupler is a RF four-port passive device, widely used in RF/microwave measurements. Applications include RF power amplifier output monitoring, transmitter power detection, RF test system inspection, transmitter-to-antenna reflected power detection, VSWR detection for antenna systems, and power control. Advantages: compact size, lightweight, and low transmission path loss.
