Pasternack Launches New Series of Mechanically Tunable Waveguide Gunn Diode Oscillators

New Oscillators Cover WR-90, WR-42 and WR-28 Waveguide Sizes and Support X, K and Ka Bands

IRVINE, Calif. – Pasternack, an Infinite Electronics brand and a leading provider of RF, microwave and millimeter wave products, has released a new line of waveguide Gunn diode oscillators that are ideal for electronic warfare, electronic countermeasures, microwave radio systems, military and commercial communications systems and more.

Pasternack’s new mechanically tunable waveguide Gunn diode oscillators cover WR-90, WR-42 and WR-28 waveguide sizes and support X, K and Ka bands. All models in this line operate at 50 ohms and incorporate a mechanical tuning screw to fine tune the output frequency for specific applications. They deliver output power levels up to +18.5 dBm typical and utilize Indium Phosphide (InP) Gunn diodes that yield higher output power, higher efficiency and lower AM noise than GaAs counterparts.

These waveguide Gunn diode oscillators feature compact package designs that are highly reliable and designed to meet MIL-STD-202 test conditions for shock, vibration, altitude and humidity. They are available in rugged compact package designs with operational temperature ranges from -40°C to +85°C.

“Our new lineup of waveguide Gunn diode oscillators is truly innovative with desirable waveguide sizes covering popular frequency bands and utilizing InP semiconductor technology that yields higher output power with higher efficiency and lower AM noise. Plus, these models are available in-stock with no MOQ,” said Tim Galla, Product Line Manager.

Pasternack’s new waveguide Gunn diode oscillators are in-stock and available for immediate shipment.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
