The Amplifier Research DC6180A 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 while the coupling factor is well matched to the typical laboratory equipment.
