Model DC7462
Dual Directional Coupler
1400 Watts CW
12GHz–18GHz
The Model DC7462 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 DC7462 is
intended for use with the 4000TP12G18 and other T series microwave TWT amplifiers.
