SOV-94202210-90-G1

Rev. 1.1

Description:
Model SOV-94202210-90-G1 is an X-Band, Varactor tuned
Gunn oscillator that utilizes a high performance GaAs Gunn
diode and proprietary cavity design to deliver +10 dBm typicalpower. The oscillator features a Varactor tuning range of ±100
MHz and delivers low AM/FM noise and harmonic emissions.
Compared to its counterparts, such as multiplier based sources,
the Gunn oscillator is a lower cost and cleaner source. Thecenter frequency of the oscillator can be mechanically trimmed
within ±50 MHz using the self-locking set screw. The
performance of the oscillator can be further enhanced by adding an isolator, Gunn oscillator
modulator/regulator and temperature heater.

Caution:• Reversing polarity will destroy the device.
• Gunn diode bias voltage should never exceed +12.0 Volts and Varactor bias voltage should neverexceed +20 Volts.
• The case temperature of the device should never exceed +85˚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.
