Aero™/Aero+ GSM/GPRS Transceiver Chipsets INTEGRATED TRANSCEIVERS FOR MULTI-BAND GSM/GPRS WIRELESS COMMUNICATIONS FEATURES • Complete multi-band GSM cellular radio front-end using 100% CMOS RF technology – GSM 850 – E-GSM 900 – DCS 1800 – PCS 1900 • Best-in-class performance • Unparalleled integration – 50% less board area – 80% fewer components • Low-IF receiver – Dual or triple band LNA – Image-reject down-converter – High performance A/D converter • Universal analog baseband interface – Digital channel select filter – Digital programmable gain control • Offset PLL transmitter PRODUCT DESCRIPTION The Aero transceiver is the industry’s first 100% CMOS RF front-end for multi-band GSM digital cellular handsets and wireless data modems. The Aero’s highly-integrated architecture eliminates the IF SAW filter, low noise amplifiers (LNAs) for three bands, – High precision I/Q up-converter – Integrated transmit VCO and loop filter • Proven frequency synthesizer technology – Integrated RF and IF VCOs transmit and RF voltage-controlled oscillator (VCO) modules, and more than 60 other • Integrated reference oscillator (DCXO) discrete components found in conventional GSM handsets to deliver smaller, more cost • GPRS class 12 compliant effective GSM solutions that are easier to design and manufacture. • 2.7 to 3.0 V operation The receive section uses a digital low-IF architecture which avoids the difficulties associated with direct conversion receivers while lowering cost and reducing complexity. The universal analog baseband interface is compatible with any baseband subsystem. • Low profile packages – Si4200: 5 x 5 mm MLP32 – Si4201: 4 x 4 mm MLP20 – Si4133T/34T: 5 x 5 mm MLP28/MLP32 The transmit section uses an offset phase-locked loop (PLL) with a fully integrated transmit VCO. The frequency synthesizer takes advantage of Silicon Labs’ proven APPLICATIONS • Multi-band GSM cellular handsets synthesizer technology to integrate RF and IF VCOs, varactors and loop filters. The Aero+ transceiver integrates a digitally controlled crystal oscillator (DCXO) to eliminate expensive and bulky VC-TCXO modules.

CMOS. UNIVERSAL. INNOVATIVE. Unparalleled Integration: The Aero transceiver’s innovative architecture eliminates the IF SAW filter, transmit and RF VCO modules and more than 60 other discrete components found in conventional GSM handset designs. This level of integration is an enabling force in lowering the cost, simplifying the design and manufacturing, and shrinking the form factor of the RF circuitry in nextgeneration GSM voice and data terminals. 100% CMOS Technology: While conventional solutions use BiCMOS or other bipolar process technologies, the Aero chipset is the industry’s first cellular transceiver to be implemented in a 100% CMOS process. This brings the dramatic cost savings and extensive manufacturing capacity of CMOS to the GSM market. Universal Baseband Interface: A software-programmable baseband interface enables the Aero transceiver to operate with any baseband subsystem. This programmability gives the handset designer the ability to use the latest RF technology without redesigning the baseband portion of the phone. Digital Low-IF Receiver: The Aero transceiver uses a patented digital low-IF receive architecture that avoids the difficult problems associated with direct conversion approaches while lowering cost, reducing complexity and ensuring consistent part-to-part operation.
