Pasternack has unveiled a new line of compact, waveguide, tunable, low phase noise, Gunn-diode oscillators at popular K- and Ka-Band frequencies. The two models in the series, both incorporating self-locking tuning screws, are:

  • The PEWGN1001, a K-Band oscillator module that generates a center frequency of 24.125 GHz with a tuning range of ±1.0 GHz
  • The PEWGN1000, a Ka-Band oscillator with a center frequency of 35 GHz and a tuning range of ±3.0  GHz.

Pasternack’s Gunn diode oscillators incorporate high performance devices assembled in 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.

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 minimum with power stability of −0.03 dB/°C maximum.

The oscillators are biased with +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 military-grade waveguide flanges of WR42 UG-595/U for K-Band and WR28 UG-599/U for Ka-Band.

Typical applications for the Gunn-diode oscillators are transmit and receive local oscillators (LO) for radio communications, sources that can be multiplied for higher mmWave frequency test and measurement, military and commercial radar sources, police radar, Doppler sensors and security screening.

Tim Galla, Pasternack product manager, said, “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.”

Pasternack’s new Gunn diode oscillators have no minimum order quantity.
