Key Features and Functions

The Amplifier Research Models DC7205 is a dual directional coupler with excellent frequency range and power handling capability. The wide range assures flexibility in coupling medium power amplifiers to oscilloscopes, voltmeters, power meters, spectrum analyzers and other measuring instruments. The dual directional design allows the user to monitor both forward and reflected power, a much needed characteristic in RF susceptibility testing for amplifier overdrive protection, field control and load protection. Low insertion loss allows efficient coupling to the load.

The Model DC7205 and DC7205A series is uniquely suited for use with our line of 0.7-6 GHz S-Series power amplifiers, other amplifiers operating within this frequency and power range, and our PM2003 power meter.
