$0

The Amplifier Research Model DC7490 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 sisceptibility testing for amplifier overdrive protection, field control and load protection. Low insertion loss allows efficient coupling to the load. The DC7490 is intended for use with the 4000TP8G12, 8300TP8G12 and other T series microwave TWT amplifiers.

  • Frequency Range: 8-12 GHz
