MODEL DC6280
DUAL DIRECTIONAL COUPLER
1500 WATTS CW
80 - 1000 MHz
The Model DC6280 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.
