Gunn Diode Oscillator Operates at 24.125 GHz

ALLEN, Texas - Fairview Microwave Inc. releases a waveguide Gunn oscillator that provides a cost-effective source for microwave power with excellent frequency and power stability while generating low-phase-noise. Typical applications include transmit and receive oscillators for radio communications, local oscillator source that can be multiplied for higher mm-wave frequency test and measurement, military and commercial radar sources, police radar, Doppler sensors and security screening.

Fairview Microwave’s model FMWGN1001 is a K-Band waveguide Gunn oscillator module that generates a center frequency of 24.125 GHz and can be tuned up to +/- 1.0 GHz via a self-locking tuning screw. Because of the extremely high external Q and temperature compensation mechanism, this design exhibits higher frequency and power stability, lower phase-noise and higher anti-load-pulling characteristics. Performance specs include phase noise of -95 dBc/Hz typical at 100 KHz offset, and frequency stability of -0.4 MHz/°C maximum. The output power of this oscillator is +10 dBm minimum with power stability of -0.04 dB/°C maximum. Bias supply is +5Vdc at 200 mA typical with an operating temperature range of -40°C to +85°C.

The design of this oscillator from Fairview utilizes high performance components in a rugged and compact aluminum package with a precision machined internal cavity design. The output frequency port supports a WR-42 UG-595/U waveguide flange interface.

Fairview’s waveguide Gunn diode oscillator is in-stock and ready for immediate shipment with no minimum order quantity. For detailed information, visit
