SNF-22-CA

Rev 1.0

Description:
Model SNF-22-CA is a full Q band, waveguide junction
circulator that covers the frequency range of 33 to 50
GHz. The full band circulator is designed andmanufactured to provide a low insertion loss of 0.6 dB
with good flatness. The circulator also offers a moderate
isolation of 16 dB for system integration. The input andoutput ports are WR-22 waveguides with UG-383/U
anti-cocking flanges. The full band isolator is offeredunder model number STF-22-S1-M. The higher isolationand narrow band models with up to 50% of the
waveguide bandwidth are offered under the product SNW with single junction and 3-junction
configurations.
