Product Overview

AMPLIFIER RESEARCH DC7144A

The Amplifier Research DC7144A 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 DC7144A is uniquely suited for use with the AR “S” series microwave power amplifiers (5S1G4, 20S1G4, 40S1G4, 80S1G4, 175S1G4), other amplifiers operating within this frequency and power range, and the PM2003 power meter.
