Nitronex Develops 190 and 240W, 48V GaN on Si Products Targeting WiMAX and LTE Applications

June 18, 2007 by Jeff Shepard

Nitronex announced the NPT25190 & NPT25240 – the first products in its upcoming 48V product line that are designed as high-power output stage devices from 2.3 – 2.7GHz. Typical performance is rated using a mobile WiMAX waveform defined as a single carrier OFDM signal 64-QAM 3/4, 8 burst, 7MHz channel bandwidth, 10.3dB PAR @ .01% probability on CCDF. Under these test conditions, the company claims that the NPT25190 will deliver 15dB of gain (typical), 22% efficiency, and less than 2.5% EVM – at >24W of power at elevated flange temperatures (>95C) required by next generation systems.

"We have tried to take into account the requirements being driven by the emerging standards in WiMAX and cellular," said Kevin Linthicum, Nitronex CTO & VP Engineering. "The 802.16E and LTE systems want to pack more power into ever smaller footprints while increasing channel bandwidth and peak to average ratio (PAR). Nitronex devices based on our SIGANTIC® process are ready to meet these challenges."

The initial products planned will be designed for WiMAX and 3G/3G LTE waveforms operating in frequency bands of 2.3 - 2.7 GHz, 48V driver devices, and parts optimized for 1.8 - 2.2GHz operation will be developed as part of this family of products. The planned availability is for initial samples in 3Q 07 and production quantities starting in 4Q 07.
