Atec DC7450 User Manual
Model DC7450,
M1 through M3
Dual Directional Coupler
3000 Watts CW
7.5GHz–18GHz
The Model DC7450 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 DC7450 is intended for use with the 200T8G18, 500T8G18, 1000T8G18, 2000TP8G12,
2000TP8G18 and other "T" series microwave TWT amplifiers.
