SOV-34305216-28-G1

AdvancedKa-Band Varactor Tuned Gunn Oscillator, 34 GHz, ±250 MHz BandwidthDescription:
Model SOV-34305216-28-G1 is a Ka-Band, Varactor tuned Gunn
oscillator that utilizes a high performance GaAs Gunn diode andproprietary cavity design to deliver +16 dBm typical power. Theoscillator features a Varactor tuning range of ±250 MHz anddelivers low AM/FM noise and harmonic emissions. Comparedto its counterparts, such as multiplier based sources, the Gunn
oscillator is a lower cost and cleaner source. The center
frequency of the oscillator can be mechanically trimmed within±250 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.

All data presented is collected by using a sample lot for illustration purpose. Actual data isdifferent unit to unit.
The data given above was tested under case temperature +35 °C.
The SAGE Millimeter Gunn oscillator regulator SOR-R3 is highly recommended for over voltage andreverse bias protection. The outline of the model SOR-R3 is shown in below.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.

Caution:•••••Reversing polarity will destroy the device.
Gunn diode bias voltage should never exceed +5.5 Volts and Varactor bias voltage should neverexceed +25 Volts.
The case temperature of the device should never exceed +50˚C. Use an additional heatsink or fan ifnecessary.
Proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm), should be applied. SAGE Millimeter torquewrench, model SCH-08008-S1, is highly recommended.
Any foreign objects in the waveguide will destroy the device.
