PE3 0.5µm MESFET Process
GaAs MESFET Foundry Service
Introduction
M/A-COM’s PE3 process utilizes molecular beam epitaxy (MBE) to implement a MESFET active layer structure
that achieves high breakdown and high efficiency for multi-watt power applications thru 18 GHz. Wafer diameter is
100 mm. The focus is on products for moderate to high volume applications. M/A-COM offers a full compliment of
foundry services to meet the requirements for custom designing a MMIC-based die or packaged product.
