SNW-9239831535-10-CM

Rev. 1.1

Description:
Model SNW-9239831535-10-CM is a W band waveguide
three-junction circulator that covers the frequency rangeof 92 to 98 GHz. The three-junction waveguide circulator
is designed and manufactured to provide a low insertion
loss of 1.5 dB and a high port isolation of 35 dB between
designated ports. The unit is offered for high port
isolation duplexing between the transmitter and receiver.
Unlike single junction circulator, the three-junction
circulator offer inherent high port insertion loss from port
3 to port 1 and slightly lower isolation from port 1 to port 3 due to its unique mechanical configuration.
The RF ports of the circulator are WR-10 waveguides with UG-387/U-M anti-cocking flange.
