Dual Directional Coupler
0.7–4.2GHz
The Model DC7154A 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 Model DC7154A is uniquely suited for use with our “S” series power amplifiers, other amplifiers operating within this
frequency and power range, and our PM2000 Series power meters.
