The Model DC3300 and DC3300A 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 DC3300 and DC3300A series is uniquely suited for use with our 100A400AM20 power
amplifiers, other amplifier 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.
