The Model DC7128A is a high power dual directional coupler with excellent frequency range and power handling capability. The wide range assures flexibility in coupling high power amplifiers to 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 DC7128A is intended for use with the 500T1G2 and 1000T1G2z5 and other "T" series microwave TWT amplifiers and other amplifiers operating within the frequency and power range.
