Aero GSM/GPRS/EDGE Transceiver

Silicon Laboratories’ family of Aero transceivers are the industry’s smallest, highest
performance transceivers for multi-band GSM/GPRS/EDGE cellular handsets and wireless
data modems. The proven architecture integrates all sensitive components, such as TX and
RF VCOs, loop filters, tuning inductors, varactors and clock coupling capacitors, into the
smallest packages in the industry. Compared to competing solutions, Aero transceivers
reduce component count and board space by half and implement an entire quad-band
radio, 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 ease
the design and manufacturing process. The Aero receiver leverages a proven digital low-IF
architecture that avoids the inherent difficulties associated with direct conversion receivers
while delivering higher performance, lower solution cost and reduced complexity. The
transmit section uses an offset phase-locked loop (OPLL) integrated with Silicon
Laboratories’ patented synthesizer technology. The software-programmable universal
baseband interface allows handset designers to implement the transceiver with all leading
basebands.
