SWC-28KF-E1-T and SWC-28KM-E1-T

Ka-Band Waveguide to K Connector Adapter, EndLaunch, Threaded HoleSWC-28KF-E1-T and SWC-28KM-E1-T are end launch (180°) Ka-Band
waveguide to coax adapters that cover the frequency range of 26.5 to 40
GHz. They are designed and manufactured for instrumentation grade
quality but offered at a commercial grade price, allowing for an efficienttransition between the rectangular waveguide and 2.92 mm (K) coax
connector. The adapter offers typical 0.25 dB insertion loss and 20 dB
return loss, respectively. The cover flange holes of the adapter arethreaded holes to improve the reliabilities for shock and vibration. Theright angle (90°) versions are offered under model numbers SWC-28KFR1-T and SWC-28KM-R1-T.

NOTE:•••On condition that test data is provided it is collected from a sample lot. Actual data may vary slightly from unit to unit. All
testing is performed under +25 °C room temperature.
On condition that simulated test data is provided, actual measured data may slightly vary.

CAUTION:••

If a waveguide is present, any foreign objects in the waveguide will cause performance degradation and may damage ordestroy the unit.
For 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, and SMA connectors proper torque should be applied: 8.0 ± 0.15 inch-pounds(0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly recommended.
