Description
Microsemi’s GaAs Gunn diodes, epi-up (anode
heatsink), are fabricated from epitaxial layers grown
at MSC by the Vapor Phase Epitaxy technique. The
layers are processed using proprietary techniques
resulting in ultra- low phase and 1/f noise. The diodes
are available in a variety of microwave ceramic
packages for operation from 9.5–35.5 GHz.

Microsemi Gunn diodes are specified to operate within a narrow range of a customer-designated center frequency within the operating frequency range shown.
Additional frequencies are available; Please contact the factory.

Power is measured using a critically coupled test cavity. For pulsed diodes, pulse width = 1 µS, duty factor = 1% typ.
3
Polarity: cathode is the cap and anode is the heatsink.
