Pasternack Debuts New Line of Compact Waveguide Gunn Diode Oscillators

385

Pasternack, a leading provider of RF, microwave and millimeter wave products, has unveiled a new line of compact waveguide Gunn diode oscillators that are tunable and generate signal levels that exhibit low phase noise at popular K and Ka band frequencies. 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.

Pasternack’s new Gunn diode oscillators incorporate high-performance devices and machined aluminum cavities.  Due to the extremely high external Q and temperature compensation mechanism, these oscillators exhibit excellent frequency and power stability, lower phase noise and higher anti-load pulling characteristics. There are two models in this series, the PEWGN1001 model is a K-Band waveguide Gunn oscillator module that generates a center frequency of 24.125 GHz with a tuning range of +/- 1.0 GHz. The PEWGN1000 model generates a Ka band center frequency of 35 GHz with a tuning range of +/- 3.0 GHz.  Both models incorporate self-locking tuning screws.

Performance specifications include phase noise as low as -98 dBc/Hz typical at 100 KHz offset and frequency stability as low as -0.2 MHz/°C maximum. The output power of these oscillators is +10 dBm min with power stability of -0.03 dB/°C maximum. Bias supply is +5 to +5.5 Vdc at 200 to 250 mA typical with an operating temperature range of -40°C to +85°C.  The rugged and compact package designs support output frequency ports with fully integrated Mil-grade waveguide flanges of WR-42 UG-595/U for K band and WR-28 UG-599/U for Ka band.

“Our new series of K and Ka band Gunn diode oscillators offer popular center point frequencies of 24.125 and 35 GHz that are tunable. Designers will find these devices extremely useful for sensitive communication, radar and test and measurement applications. Pasternack offers both models available in stock with detailed datasheets and ready for immediate shipment,” said Tim Galla, Product Manager.
