SOV-50305215-19-G1

Rev. 1.1

Description:
Model SOV-50305215-19-G1 is a U-Band, Varactor tuned Gunn
oscillator that utilizes a high-performance GaAs Gunn diode andproprietary cavity design to deliver +15 dBm typical power. Theoscillator features a Varactor tuning range of ±500 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. The performance of the oscillator
can be further enhanced by adding an isolator, Gunn oscillatormodulator/regulator and temperature heater.

U-Band Varactor Tuned Gunn Oscillator, 50 GHz, 1 GHz BandwidthBandwidthCaution:• Reversing polarity will destroy the device.
• Gunn diode bias voltage should never exceed +4.5 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. Eravant torque wrench,model SCH-08008-S1, is highly recommended.
• Any foreign objects in the waveguide will destroy the device.
