Microsemi Wireless LAN Power Amplifiers Chosen for Synad Dual-Band WLAN Reference Designs

IRVINE, Calif.--Oct. 20, 2003--

  -- Amplifiers Used in Reference Designs for Dual 802.11a/b/g Applications  

-- Synad is a Leading Developer of Innovative Multimode Chipset Solutions for High Performance WLANs

Microsemi Corp. , a leading manufacturer of power management integrated circuits, announced today that two of its advanced InGaP HBT power amplifiers have been chosen by Synad, Reading, UK, for reference designs provided with its dual band SY8000 WLAN chipsets.

Synad's flexible SY8000 chipset concurrently supports multiple standards via a single integrated dual-band radio and provides OEMs with a software platform to incorporate value-added features and extensions. The solution features patented "band interleaving" to bring dual-band 2.4 GHz (IEEE 802.11b and IEEE 802.11g) and 5GHz (IEEE 802.11a) WLAN equipment costs comparable with 2.4GHz-only equipment.

Synad customers will use its highly integrated reference designs to develop individual client, gateway and network infrastructure products incorporating the SY8000 chipset.

"Microsemi's power amplifiers provide the performance and integration levels we require to maintain our strong position in the fast-growing dual-band wireless LAN market," said Ashoc Dhuna, chief technology officer, Synad.

The new Synad reference designs include Microsemi's LX5512E(TM) amplifier for 802.11b/g and the LX5506(TM) amplifier for 802.11a applications. Both Microsemi amplifiers were designed in an advanced InGaP/GaAs HBT RFIC fabrication process that allows them to consume minimal current while providing sufficient gain to achieve the required output power and linearity required in 64 QAM systems at 54Mbps.

"Being part of quality reference designs such as the new release from Synad is a key element in Microsemi's plan for addressing the wireless LAN market," said James J. Peterson, Microsemi president and chief executive officer. "Our people work very hard to help them reach their performance goals while saving power," he said. Power amplifiers are key to determining the range, bandwidth and power consumption of WLAN systems.
