Product Overview
Mini-Circuits SYDC-20-31HP+ high-power bi-directional coupler provides high power handling up to 50W and low mainline loss
of only 0.1 dB. Covering frequencies from 1.5 to 30 MHz, it supports a variety of signal monitoring and measurement applica-
tions. High directivity of 33 dB provides very low measurement error from the coupled port and 25 dB typical input/output return
loss provides excellent matching over the specified band. This model features core and wire construction with wrap-around
terminations for good solderability and easy visual inspection.
