New series of mechanically tunable waveguide Gunn diode oscillators

Pasternack has released a new range of waveguide Gunn diode oscillators that are ideal for electronic defence, electronic countermeasures, microwave radio systems, defence and commercial communications systems and more.

Its new mechanically tunable waveguide Gunn diode oscillators include WR-90, WR-42 and WR-28 waveguide sizes and support X, K and Ka bands. All models in this range operate at 50-Ohm and include a mechanical tuning screw to fine tune the output frequency for particular applications. They produce output power levels up to +18.5dBm typical and use InP Gunn diodes that produce higher output power, higher efficiency and lower AM noise than GaAs counterparts.

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

“Our new lineup of waveguide Gunn diode oscillators is truly innovative with desirable waveguide sizes covering popular frequency bands and utilising 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.
