Nitronex Corp. (Raleigh, NC) also is known for its GaN work. Back in 2001, the company made
headlines when it announced that it was producing GaNbased high-electron mobility transistors
(HEMTs) on 4-in. rather than 2-in. silicon wafers. The company has continued its GaN developments
ever since. This past March, it released a 50-W, 28-V GaN HEMT that is designed for WiMAX
applications with frequencies from 3.3 to 3.8 GHz. For Vds = 28 V, Idq = 750 mA at a center frequency
of 3.5 GHz. To provide broadband performance, the device offers input-only matching and no output
matching. The PNPT35050 was built using the SIGANTIC GaN-on-Si platform technology.
