SOM-90305213-10-S1

Rev. 1.1

Description:
Model SOM-90305213-10-S1 is a W-band, mechanically tuned
Gunn oscillator that utilizes a high-performance GaAs Gunn
diode and proprietary cavity design to deliver +13 dBm typicalpower. The oscillator features a frequency tuning range of 89.75
to 90.25 GHz and delivers low AM/FM noise and harmonic
emissions. Compared to its counterparts, such as multiplierbased sources, the Gunn oscillator is a lower cost and cleaner
source. The Gunn oscillator’s frequency can also be tuned by varying the bias voltage, which is useful forphase-locking and electrical-tuning applications. The Gunn oscillator is equipped with a self-locking set
screw for frequency trimming. Models with a micrometer for lab and test bench applications areavailable under a different model number. The performance of the oscillator can be further enhancedby adding an optional isolator, Gunn oscillator modulator/regulator and temperature heater.

Caution:• Reversing polarity will destroy the device.
• Bias voltage should never exceed +5.5 Volts.
• The case temperature of the device should never exceed +50˚C. Use an additional heatsink or fan ifnecessary.
• Proper torque, 8.0 ± 0.4 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.
