Description

Wolfspeed’s CMPA5259025S is a gallium-nitride (GaN) HEMT-based monolithic microwave

integrated circuit (MMIC). GaN has superior properties compared to silicon or gallium

arsenide allowing the technology to offer greater power density and wider bandwidths

compared to Si and GaAs devices. This MMIC uses a two-stage reactively matched amplifier

design approach enabling wide bandwidths to be achieved in a small-footprint, while

maintaining high gain and efficiency. Operating at 28 V, the 40 W pulsed output power

is designed primarily for use as an output stage for highly integrated AESA radar type

architectures. In addition the high gain makes it suitable as a drive stage for a multi-device

line-up using the Wolfspeed high power IMFETs as the final stage.
