Silicon Laboratories’ family of Aero transceivers are the industry’s smallest, highestperformance transceivers for multi-band GSM/GPRS/EDGE cellular handsets and wirelessdata modems. The proven architecture integrates all sensitive components, such as TX andRF VCOs, loop filters, tuning inductors, varactors and clock coupling capacitors, into thesmallest packages in the industry. Compared to competing solutions, Aero transceiversreduce component count and board space by half and implement an entire quad-bandradio, excluding the power amplifier and antenna switch, in a footprint as small as 1.0 cm2.Delivering industry-leading performance, Aero transceivers improve call quality and easethe design and manufacturing process. The Aero receiver leverages a proven digital low-IFarchitecture that avoids the inherent difficulties associated with direct conversion receiverswhile delivering higher performance, lower solution cost and reduced complexity. Thetransmit section uses an offset phase-locked loop (OPLL) integrated with SiliconLaboratories’ patented synthesizer technology. The software-programmable universalbaseband interface allows handset designers to implement the transceiver with all leadingbasebands.
