LX5543 ® TM 2.4-2.5 GHz Front-End Module with Internally Matched Power Amplifier and SP3T Switch P RODUCTION D ATA S HEET KEY FEATURES DESCRIPTION provides about 25dB power gain, and +17dBm linear output power, with EVM (<3%) for 64QAM/ 54Mbps OFDM. Both gain and power are readily measured at antenna port, with the insertion loss of the SP3T switch included. The Rx path of LX5543 features low insertion loss of 0.6dB and high input referred 1dB gain compression point (IP1dB) of +25dBm. Bluetooth path of LX5543 features insertion loss 0.9dB, and IP1dB of +29dBm. LX5543 is available in a 16-pin, low profile of 0.55mm, 3x3mm2 microlead package (MLPQ-16L). With its high level of functional integration, best-class performance, compact footprint and low profile, LX5543 offers an ideal front-end solution for the ever demanding design requirements of today’s highly integrated mobile equipments, including 802.11 b/g/n and Bluetooth applications.
