SAT-F3-34034-S1
WR-34 Orthomode Transducer, 22 to 33 GHz
SAT-F3-34034-S1 is a WR-34 orthomode transducer (OMT)
that operates between 22 to 33 GHz. The OMT separates acircular or elliptical polarized waveform into two linear, orthogonal
waveforms or combines two linear polarized waveforms into one
circular or elliptical polarized waveform or vice versa. The OMTalso supports either vertical or horizontal polarized waveguideforms. The OMT shows high port isolation while providing
a low insertion loss. The OMT is configured with a 0.340” x0.340” square waveguide for the antenna port and two WR-34
waveguides for the horizontal and vertical ports. All ports havestandard UG-1530/U flange with 4-40 threaded holes.

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.
Eravant reserves the right to change the information presented without notice.

CAUTION:••••

If a waveguide is present, any foreign objects in the waveguide will cause performance degradationand may damage or destroy the unit.
Any foreign objects in the antenna will cause performance degradation and possible device
damage.
For 1 mm connectors proper torque should be applied: 4.0 ± 0.15 inch-pounds (0.45 ± 0.02 Nm).
Torque wrench model SCH-06004-S1 is highly recommended.
For 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, and SMA connectors proper torque should beapplied: 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm). Torque wrench model SCH-08008-S1 is highly
recommended.
