Waveguide Gunn Diode Oscillators from Pasternack

Pasternack’s Gunn diode oscillators incorporate high performance devices and machined aluminum cavities.  Due to the extremely high external Q and temperature compensation mechanism, these Gunn Diode oscillator’s exhibit excellent frequency and power stability, lower phase noise and higher anti-load pulling characteristics.

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.
