PRODUCT DESCRIPTION
The Aero transceiver is the industry’s most integrated RF front-end for dual and triple band
GSM digital cellular handsets and wireless data modems. The highly integrated solution
eliminates the IF SAW filter, low noise amplifiers (LNAs) for three bands, transmit and
RF voltage controlled oscillator (VCO) modules, and more than 60 other discrete
components found in conventional GSM handset designs.
The receive section uses a digital low-IF architecture which avoids the difficulties
associated with direct conversion receivers while delivering on the promises of lower cost
and reduced complexity. The universal analog baseband interface is compatible with any
supplier’s baseband subsystem. The transmit section is a complete up-conversion path
from the baseband subsystem to the power amplifier, and uses an offset phase-locked
loop (PLL) with a fully integrated transmit VCO. The frequency synthesizer uses Silicon
Labs' proven technology, which includes integrated RF and IF VCOs, varactors, and
loop filters.

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 next-
generation 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 inter-
face enables the Aero transceiver to oper-
ate with any baseband subsystem. This
programmability gives the handset design-
er 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 digi-
tal low-IF receive architecture which avoids
the difficult problems associated with direct
conversion while delivering the promises
of lower cost and reduced complexity.
