IRVINE, Calif., Dec. 8, 2008 (GLOBE NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, today announced production of its LX5537 power amplifier (PA) for IEEE 802.16e WiMAX and WiBro 4G wireless applications using the 2.3GHz to 2.9GHz frequency range. Among the world's most efficient WiMAX PAs, Microsemi's LX5537 delivers 23 percent power-conversion efficiency and extends the company's proven RF wireless LAN portfolio into a variety of next-generation wireless network applications.
"With engagements at the leading 4G OEMs, our new LX5537 WiMax power amplifier solves the common problems encountered in mobile and customer premises equipment (CPE) WiMAX designs including challenging performance requirements, solution cost and PCB area," said Kang Hee Kim, RF product line manager at Microsemi's Analog Mixed Signal Group. "Leveraging our system perspective, our WiFi and WiMAX PAs offer superior performance without compromising board size and bill of materials costs. The LX5537 joins our successful line of 802.11a/b/g and 802.11n power amplifiers in Microsemi's RF portfolio."
Offered in a 3x3mm 16L QFN package, the LX5537 features an on-chip output power detector to implement power control with minimum BOM cost and PCB area. The 26dB attenuation function can optionally be used to reach low gain mode.
