SNW-9439631535-10-CM

Rev. 1.2

Description:
Model SNW-9439631535-10-CM is a W band waveguide
three-junction circulator that covers the frequency rangeof 94 to 96 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 three-junction circulator is offered
for high port isolation duplexing between the transmitterand receiver. Unlike single junction circulator, the threejunction circulator offer inherent high port insertion lossfrom port 3 to port 1 and slightly lower isolation from port 1 to port 3 due to its unique mechanicalconfiguration. The RF ports of the circulator are WR-10 waveguides with UG-387/U-M flanges.
