BAE Systems has developed the world’s first 0.1µm 6” 2-mil PHEMT MMIC process with high power, high yield and excellent reliability.  Utilizing T-gate technology and 2-mil substrates, we have created a millimeter wave technology producing excellent performance from Ka-band through W-bands.  DC and RF characteristics have excellent uniformity across the wafer with very high spec yield.  Due to the excellent reliability and performance characteristics, the developed HPA technology provides a low cost advantage for millimeter-wave applications.
