Features
The Models DC7210A & DC7210 are dual directional couplers 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 DC7210A/DC7210 series
is uniquely suited for use with our 0.7-6 GHz, 350S1G6 A
power amplifier or other amplifiers operating within this frequency and power range.
The export classification for this equipment is EAR99. These commodities, technology or software
are controlled for export in accordance with the U.S. Export Administration Regulations. Diversion
contrary to U.S. law is prohibited.
