Model DC7275A, M1

Model DC7275, M1, M2

Dual Directional Coupler

700 Watts CW

2.5GHz–7.5GHz

The Model DC7275A is a high power dual directional coupler with excellent frequency range and power

handling capability. The wide range assures flexibility in coupling high power amplifiers to 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 DC7275A is intended for use with the 500T2G8 and other “T” series microwave amplifiers.
