SOM-94304316-10-S1-H

Rev. 1.0

Description:
Model SOM-94304316-10-S1-H is a W-band, mechanically tuned Gunn
oscillator that utilizes a high-performance GaAs Gunn diode andproprietary cavity design to deliver +16 dBm typical power. Theoscillator features a frequency tuning range of 92 to 96 GHz anddelivers low AM/FM noise and harmonic emissions. Compared to its
counterparts, such as multiplier-based sources, the Gunn oscillator is alower cost and cleaner source. The Gunn oscillator’s frequency canalso be tuned by varying the bias voltage, which is useful for phaselocking and electrical-tuning applications. The Gunn oscillator is equipped with a self-locking set screw
for frequency trimming and a heater for temperature stability. Models with a micrometer for lab andtest bench applications are available under a different model number. The performance of the oscillator
can be further enhanced by adding an optional isolator and Gunn oscillator modulator/regulator.

Note:• All data presented is collected from a sample lot. Actual data may vary unit to unit, slightly.
• 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.
• The bias tuning feature can be used for electrical tuning and phase lock loop applications.
• SAGE Millimeter, Inc. reserves the right to change the information presented without notice.
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 ± 0.15 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.
