SYDC 50Ω SMD Bi-Directional Couplers

Mini-Circuits SYDC 50Ω SMD Bi-Directional Couplers offer high 25W (SYDC-20-62HP+) or 50W (SYDC-20-31HP+) power handling, 20dB coupling, and low mainline losses. These components support a wide range of operating requirements in the 1.5MHz to 30MHz and 10MHz to 540MHz frequency ranges. The SYDC Bi-directional Couplers allow accurate sampling of signals on the forward path and the reflected path in RF/microwave systems and test applications.
