PEWGN1010

Overview

The PEWGN1010 is a mechanically tuned Gunn diode oscillator manufactured by Pasternack. It operates in the Ka-band with a center frequency of 35 GHz and a tuning range of +/- 3.0 GHz. The device delivers an output power of +15 dBm and utilizes a WR-28 waveguide interface. It functions on a typical bias supply of +5 to +5.5 Vdc at 200–250 mA, supporting a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Mechanically tuned operation using a self-locking tuning screw for stable frequency adjustment
• High external Q-value design providing superior frequency and power stability
• Temperature compensation mechanism ensuring low phase noise and high load-pull immunity
• Durable machined aluminum cavity construction suitable for harsh environments

Applications

• Radio communication transceiver oscillators
• Local oscillator sources for high-frequency test and measurement equipment
• Military and commercial radar systems
• Police radar and Doppler sensors
• Security screening applications

Procurement Notes

Verify the specific mechanical tuning interface and waveguide flange type (WR-28) against system requirements before procurement. Confirm that the required tuning range of +/- 3.0 GHz aligns with the application's frequency needs. Ensure the power supply provides the specified +5 to +5.5 Vdc within the 200–250 mA current range. Check environmental specifications to ensure compatibility with the intended operating temperature range of -40°C to +85°C.

Selection Notes

Select this component when a tunable local oscillator source is required for Ka-band applications. The PEWGN1010 is appropriate for designs needing a center frequency of 35 GHz with significant tuning flexibility. Consider its compact waveguide form factor for integration into space-constrained radar or communication modules. Evaluate the need for mechanical tuning versus electronic alternatives based on phase noise and stability requirements.

Part Context

This oscillator belongs to Pasternack's series of small-form-factor waveguide Gunn diode oscillators designed for K and Ka bands. These devices are engineered to provide low phase noise and high stability in a rugged package. The series supports various military and commercial applications requiring reliable signal generation at millimeter-wave frequencies.

Replacement Considerations

The PEWGN1000 is a similar model within the same product family, also centered at 35 GHz but with a different tuning range specification. Verify if the +/- 3.0 GHz tuning requirement can be met by alternative models or if the specific mechanical tuning characteristics of the PEWGN1010 are mandatory for the design.
