The Model DC7435A and DC7435 series are wide-band dual directional couplers intended for use
with the 20S4G18, 40S4G18 and other S-Series microwave amplifiers operating within the frequen-
cy and power range. The wide frequency range assures flexibility in coupling high power amplifiers
to power meters, spectrum analyzers, receivers, and other measuring instruments. The dual direc-
tional design allows the user to monitor both forward and reflected power, a much needed charac-
teristic in RF susceptibility testing for amplifier overdrive protection, field control, and load protection.
Low insertion loss allows efficient coupling to the load.
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.
