MODEL DC6380, M1, M2
DUAL DIRECTIONAL COUPLER
3000/4500/7000 WATTS CW
80 - 1000 MHz
The Model DC6380 is a dual directional coupler with 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 while the coupling factor is well matched to typical laboratory equipment.
The DC6380 series is ideally suited for use with the AR Worldwide Model 2000W1000A, 3000W1000A,
4000W1000A and other high power amplifiers in this frequency range.
