HIGH POWER CIRCULATORS
FEATURES:
• High isolation
• Low insertion loss
• High Power Handling
APPLICATIONS:
• Assemblies and subsystems
• TWT Protection
• Duplexer in transceivers
DESCRIPTION
Millitech series HPC junction ferrite devices
(circulators) cover the frequency range
from 18 to 110 GHz. The circulator is a
four-port, differential phase shift device
which can be configured as an isolator by
terminating two of the ports. The high
isolation, low insertion loss, low VSWR
(high return loss), and high power handling
typical of these ferrite devices make them
ideal for use with frequency sources,
amplifiers, and receivers.
Also available from Millitech are low-tomedium
power isolators and circulators.
See series JFD for narrow-band low-loss
circulators and isolators. Series FBI/WBI
are full and wideband isolators. Millitech
also manufactures quasioptical Faraday
rotation duplexers. Contact Millitech sales
with your specific application requirements.
