Description
Coaxial Dual directional coupler SOH-T-20180-30, operating from 2.0 to 18.0GHz, has a 30dB coupling with N Type Female connector on coupling output and 50Ohm impedance. The dual directional design allows the user to monitor both forward and reflected power by the coupled connectors on the oppsite sides.The maximum insertion loss of the coupler is 0.6dB, maximum accuracy of coupling is ±1.0dB and maximum VSWR is 1.5:1. The directivity of the coupler is 10dB. It can handle 400W continuously and 3KW peak power. The A-INFO's coaxial dual directional coupler is manufactured with a high precision machining process to ensure high quality and ruggedness. This coupler is ideally suited for power sampling, amplifier load protection, measurement, communications, SATCOM and other applications.
