Nitronex extends 5W GaN-on-Si RF power transistor to 5.1-5.8GHz

To coincide with this week's WiMAX World event in Chicago, Nitronex of Durham, NC, USA, which manufactures gallium nitride on silicon (GaN-on-Si) RF power transistors for the commercial wireless infrastructure, broadband and military markets, says that it has expanded the performance data of its 28V, 5W-class NPTB00004 high-electron-mobility transistor (HEMT), which was launched in November 2007, to include higher frequencies of 5.1-5.2GHz and 5.7-5.8GHz (beyond the 3.5GHz originally detailed).

The NPTB00004 achieves 27dBm (400mW) average output power at 2% error vector magnitude (EVM) in 5.2GHz WiMAX systems, and 28dBm (630mW) average output power at 2% EVM in 5.8GHz WiMAX systems (single-carrier orthogonal frequency-division multiplexing (OFDM), 64-QAM 3/4, 8-burst, 20ms frame, 15ms frame data, 3.5MHz channel bandwidth, peak/average = 10.3dB).

"This data on the NPTB00004 provides our customers with an ideal solution for WiMAX applications in the 5GHz band of operation," claims Ray Crampton, director of marketing. The NPTB00004 is a versatile product that, combined with other broadband devices from Nitronex, allows designers to develop power amplifiers for multiple frequency bands using a common power device lineup, he adds.

The transistors are packaged in a cost-effective plastic over-molded PO150S (similar to a SOIC-8) package with an exposed thermal pad. Samples and application boards are available. Typical pricing is $9 each in quantities of 1000.
