Nitronex's 5W GaN on Si RF Power Transistor Ready for Volume Production

GaN pre-driver completes full amplifier line-up...

Durham, N.C. (November 12, 2007) - Nitronex, the global leader in gallium nitride on silicon (GaN on Si) RF power transistors for the wireless infrastructure, broadband and military markets, has developed a 28V, 5W class high electron mobility transistor (HEMT) designed for broadband applications from DC - 6.0 GHz. Designed using Nitronex's patented SIGANTIC® NRF1 process, the NPTB00004 achieves 250 mW average output power at 1% EVM in 3.5GHz WiMAX systems (single carrier OFDM, 64-QAM ¾, 8 burst, 20 ms frame, 15ms frame data, 3.5MHz channel bandwidth, peak/avg = 10.3dB).

"Having seen market demand for full transmitter lineups based on GaN technology we developed the NPTB00004, an excellent pre-driver for our higher power products such as the NPT25100. Combined with other broadband Nitronex devices, this device allows designers to develop power amplifiers for multiple frequency bands using a common power device lineup," said Ray Crampton, Director of Marketing at Nitronex. "The NPTB00004 is production ready and our qualification report is available online."

The NPTB00004 transistors are packaged in a cost-effective plastic over-molded SOIC-8 package with an exposed thermal pad. Samples and application boards are available. Typical pricing is $9 each in quantities of 1000, with a lead time from stock to ten weeks.

The NPTB00004 transistors are lead-free and RoHS compliant.
