MODEL DC7275A
MODEL DC7275
M1, M2
DUAL DIRECTIONAL COUPLER
700 WATTS CW
2.5 - 7.5 GHz
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 prote ction, 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.
