W-Band Varactor Tuned Gunn Oscillator, 92 to 96 GHz, +10 dBm
Description:
Model SOV-94304310-10-G1 is a W-Band Varactor tuned Gunnoscillator that utilizes a high performance GaAs Gunn diode andproprietary cavity design to deliver +10 dBm typical power. Theoscillator features a Varactor tuning range of ±2 GHz and delivers low
AM/FM noise and harmonic emissions. Compared to its counterparts,
such as multiplier based sources, the Gunn oscillator is a lower costand cleaner source. The center frequency of the oscillator can bemechanically trimmed within ±250 MHz using the self-locking set
screw. The performance of the oscillator can be further enhanced byadding an isolator, Gunn oscillator modulator/regulator and temperature heater.

Note:• All data presented is collected from a sample lot. Actual data may vary unit to unit.
• All testing was performed under +35 °C case temperature.
• 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 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 andVaractor bias voltage should never exceed +30 Volts.
• The case temperature of the device should never exceed +50 ˚C. Usean additional heatsink or fan if necessary.
• Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.05 Nm), should beapplied. SAGE Millimeter torque wrench, model SCH-08008-S1, ishighly recommended.
• Any foreign objects in the waveguide will destroy the device.
