Mini-Circuits DDCH-50-13+ is a high-power (120W), wide band (20-1000MHz) dual-directional coupler which features low insertion loss (0.15 dB), 50 dB coupling and excellent mainline return loss (30 dB). The Dual directional design allows monitoring forward and reverse power and guarantees good directivity, flatness and coupling accuracy.
The DDCH-50-13+ supports a wide variety of applications from military to VHF/UHF radio, various cellular base station applications and more.
The coupler is fabricated using laminated PCB process (1.5 x 1.0 x 0.128”) and includes wrap-around terminations for good solderability and easy visual inspection.
