AR DC7215, Operating And Service Manual

The Model DC7215 and DC7215A series are dual directional couplers with excellent frequency 

range and power handling capability.  The wide range assures flexibility in coupling high power am-
plifiers to oscilloscopes, voltmeters, power meters, spectrum analyzers and other measuring instru-
ments.  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 DC7215 and DC7215A series is uniquely suited for use with our line of 0.7–6 GHz S-
Series power amplifiers, other amplifiers operating within this frequency and power range, and our 

PM2003 power meter. 
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.
