DC6440

The Model DC6440 is a dual directional coupler with an excellent frequency range and power handling capability. The wide range assures flexibility in coupling high 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.
