SOV-88305216-10-G1

Rev. 1.0

Description:
Model SOV-88305216-10-G1 is a W-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 and delivers
low AM/FM noise and harmonic emissions. Compared to its
counterparts, such as multiplier based sources, the Gunn oscillator isa lower cost and cleaner source. The center frequency of theoscillator can be mechanically trimmed within ±250 MHz using theself-locking set screw. The performance of the oscillator can befurther enhanced by adding an isolator, Gunn oscillator modulator/regulator and temperature heater.

Note:• All data is presented using a limited sample lot, actual data may vary 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 (0.92 ± 0.05 Nm), should be applied. SAGE Millimeter torquewrench, model SCH-08008-S1, is highly recommended.
• Any foreign objects in the waveguide will destroy the device.
