IRVINE, Calif., July 5, 2005 (PRIMEZONE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog and mixed signal integrated circuits, announced today that its high performance 802.11a/b/g power amplifiers are in reference designs supporting the latest series of dual-band wireless LAN chipsets from Realtek Semiconductor Corp. of Hsinchu, Taiwan.
Microsemi integrated circuits that support the new Realtek chipsets include power amplifiers designed for IEEE802.11a/b/g WLAN applications and a fixed/adjustable voltage linear regulator that combines low dropout, high accuracy, ultra low ground current and fast response.
Microsemi WLAN power amplifiers-- designed for an advanced InGaP/GaAs HBT manufacturing process-- feature active bias, power detection, on-chip input/interstage matching plus the low current consumption required in portable applications.
"These reference designs by Realtek underscore Microsemi's position as an active participant in the highly competitive wireless LAN chipset arena," said Paul Bibeau, Sr. Vice President and General Manager of Microsemi's Integrated Circuits Group. "We are widely recognized as a market leader for the performance benefits derived from our advanced InGaP/GaAs HBT wireless LAN products."
The Realtek advanced chipsets, which provide dual 2.4GHz and 5GHz performance, were designed to take advantage of economical 0.18 micron CMOS production. "Our goal is to provide customers with more economic and competitive solutions for their wireless LAN applications," said Thomas Chou, Product Planning and Marketing Manager for Realtek. By choosing Microsemi power amplifiers, Realtek gains a cost effective solution with superior performance, especially in the demanding 5GHz band.
Realtek's new chipsets provide dual band (11a/b/g) functionality at a price point that so far has only been seen on single band (11b/g) implementations, thus enabling the SOHO/home market to take advantage of a far greater number of available channels that come in the 5GHz band. Significantly, it also avoids interference from competing applications such as Bluetooth, cordless phones and microwave ovens, which co-exist in the same 2.4GHz band.
"We are convinced that this will help move the 802.11a 5GHz standard to the forefront of the WLAN market--something that gives customers superior range and performance compared to the b/g solutions. Increased adoption of dual band solutions has been gaining momentum as predicted by experts in this field for quite some time," Chou said.
