Microsemi Corp. (Irvine, CA), a leading manufacturer of discrete semiconductors and power management integrated circuits, announced that two of its advanced InGaP HBT power amplifiers (PAs) have been chosen by Synad (Reading, UK) for reference designs provided with its dual-band, SY8000 wireless local area network (WLAN) chipsets.
Synad's SY8000 chipset concurrently supports multiple standards via a single integrated, dual-band radio and provides a software platform to incorporate value-added features and extensions. The solution features patented "band interleaving" to bring dual-band. 2.4GHz (IEEE 802.11b and IEEE 802.11g) and 5GHz (IEEE 802.11a) WLAN equipment costs comparable with 2.4GHz-only equipment.
The new Synad reference designs include Microsemi's LX5512E™ 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.
