RFMD live demo of GaN HEMTs at IEEE MTT-S show

RFMD will conduct a live demonstration of its GaN HEMT high-power transistor line-up for UMTS and will display its latest performance results for WiMAX applications at IEEE MTT-S International Microwave Symposium 2006 in San Francisco, June 13-15, 2006, at Booth 1207.

The demonstration will feature RFMD's new GaN HEMT high-power transistor line-up deployed in a digital pre-distortion system. Digital pre-distortion improves the linear efficiency performance of the high power transistor line-up with error correction for wireless infrastructure applications. RFMD will highlight latest performance data. The attraction of GaN over LDMOS and other III-Vs is the potential improvement in drain efficiency performance and power output and at the same time easing the thermal management as the devices can run satisfactorily at a higher temperature. However, while other major companies such as Eudyna are on the trail of commercialising GaN HEMTs for this application, progress has been slower than some expected. Technical refinement is required but designers must also become more confident with the new approach as a design solution and be assured that reliability is to the required standard.
RFMD has been selected by the IMS to present two technical papers focused on GaN technology, including:

- WE3B-3 "Performance and RF Reliability of GaN-on-SiC HEMTs Using Dual-Gate Architectures", Rama Vetury. This paper will be presented on June 14, from 1:20-3:00 p.m. PT at Moscone 304.

- TH1B-3 "Linearity and Efficiency Performance of GaN HEMTs with Digital Pre-Distortion Correction", Matthew Poulton. This paper will be presented on June 15, from 8:00-9:40 a.m. PT at Moscone 304.

RFMD's portfolio of highly integrated RF components and system solutions includes its industry-leading transmit modules and power amplifiers for GSM/GPRS, GSM/GPRS/EDGE, CDMA and WCDMA handsets, the Company's POLARIS TOTAL RADIO transceiver solutions for GSM/GPRS and GSM/GPRS/EDGE handsets, and its highly-integrated Bluetooth, WLAN and GPS solutions.
