SOV-94306310-10-G1

W-Band Varactor Tuned Gunn Oscillator, 94 GHz, 6 GHz
Bandwidth
SOV-94306310-10-G1 is a W-Band, Varactor tuned Gunn oscillator thatutilizes a high performance GaAs Gunn diode and proprietary cavity
design to deliver +13 dBm typical power. The oscillator features aVaractor tuning range of ±3 GHz and delivers low AM/FM noise andharmonic emissions. Compared to its counterparts, such as multiplierbased sources, the Gunn oscillator is a lower cost and cleaner source.
The center frequency of the oscillator can be mechanically trimmed
within ±100 MHz using the self-locking set screw. The performance ofthe oscillator can be further enhanced by adding an isolator, Gunn
oscillator modulator/regulator and temperature heater.

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 +35 °C room temperature.
Gunn oscillator regulator SOR-R3 is highly recommended for over voltage and reverse bias protection. The outline of themodel SOR-R3 is shown in below.
Eravant reserves the right to change the information presented without notice.
+VvCAUTION:••••••

Reversing polarity will destroy the device.
Gunn diode bias voltage should never exceed +5.5 Volts andVaractor bias voltage should never exceed +30 Volts.
The case temperature of the device should never exceed +50˚C.
Use an additional heatsink or fan if necessary
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.
