The Model DC7445 is a dual directional coupler with excellent frequency range and power handling
capability. The wide range assures flexibility in coupling power amplifiers to receivers, network analyz-
ers, 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 sus-
ceptibility testing for amplifier overdrive protection, field control and load protection. Low insertion loss
allows efficient coupling to the load.
The Model DC7445 is intended for use with 250T6G18 and other T Series microwave TWT amplifiers.
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.
