Fairview Gunn diode oscillator operates at 24.125 GHz

Feb. 21, 2017

Allen, TX. Fairview Microwave Inc., a supplier of on-demand microwave and RF components, has released a waveguide Gunn oscillator that provides a cost-effective source for microwave power with frequency and power stability while generating low phase noise. Typical applications include transmit and receive oscillators for radio communications, local oscillator sources that can be multiplied for higher mmWave 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 +5 VDC 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.

“Our FMWGN1001 Gunn oscillator module offers designers a cost-effective and high-performing K-band waveguide frequency source solution for use with sensitive communications, radar, and test and measurement applications,” explained Randy Leenerts, senior RF engineer at Fairview Microwave.

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