IRVINE, Calif.--(BUSINESS WIRE)--Sept. 16, 2002-- -- Performance, small size, broadband cited.
-- Current use reduced to less than 150mA.
Microsemi Corp. (Nasdaq:MSCC - News), a leading manufacturer of power management integrated circuits, today announced that its Integrated Products operation has introduced what it believes to be the most efficient two-stage broadband power amplifier for wireless local area network (WLAN) systems on the market today. Power amplifiers are critical in determining the range, data rate performance and power consumption of WLAN systems.

Designated the LX5503E(TM), the new two-stage amplifier targets 4.8-5.85GHz, medium-gain requirements found in the wireless LAN NIC cards and access points of IEEE 802.11a/b/g, HiperLAN2 and U-NII (FCC Unlicensed National Information Infrastructure) applications.
In addition to supporting traditional 5.15 to 5.85GHz unlicensed frequency bands, the LX5503E amplifier extends its range to 4.8GHz, accommodating the recently proposed band allocation in Japan.
"We developed this amplifier to address the low-power consumption needs for client card applications in the laptop computer market," said Paul Bibeau, Microsemi marketing vice president. "Of course the significant power reduction now available in the LX5503E will benefit other 802.11a portable designs as well," he added.
The LX5503E uses a total current of 150mA while providing a power gain of 21dB, operating at 5.25GHz and an orthogonal frequency division multiplex (OFDM) output power level of 18dBm. EVM is specified at 3.5% at full 64QAM and 54Mb/s.
Launch of the LX5503E follows rapidly on the heels of Microsemi's successful introduction of the LX5503(TM) two-stage amplifier in May, which already has become a standard implementation for wireless LAN client cards, as validated in the reference design of the industry's earliest second-generation 5GHz WLAN chipset.
"Wireless LAN chipsets continue to be a bright spot for semiconductors," said James J. Peterson, Microsemi president and chief executive officer, noting that most projections show a compound annual growth rate exceeding 50% in units and between 20-25% in dollars between 2000 and 2005. Power amplifiers are used in a ratio of at least 1:1 with WLAN chipsets.
Designed in an advanced InGaP/GaAs HBT RF integrated circuit fabrication process, the LX5503E features a single 3.3V supply, active bias for excellent thermal performance, simple input/output pre-matching for easy design implementation, plus a space-saving micro-lead package with a footprint only 3mm square and 0.9mm high.
The LX5503E power amplifier is available for immediate sampling and pre-production quantities, with pricing below $3 in 10k lot quantities. Microsemi will be able to support full customer production needs by the end of September. Complete technical information on the LX5503E and Microsemi's full line of wireless LAN product offerings is available on the Microsemi Web site, www.microsemi.com. Samples can be ordered through this site, Microsemi sales representatives or a franchised distributor.
