Model DC6280, M1A, M2, M3, M4, M5, M6
Dual Directional Coupler
1500 Watts CW
80-1000 MHz.
The Model DC6280A 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 Model DC6280A is uniquely suited for use with our “W” series high power amplifiers, other amplifiers operating
within this frequency and power range, and our PM2002 power meter.
