Silicon Laboratories introduced the Aero GSM transceiver chipset, which is based on the company's CMOS RF technology. The Aero chipset provides a complete RF front end for dual and triple band GSM digital cellular handsets. The highly integrated solution eliminates the IF SAW filter, external low noise amplifiers (LNA) for three bands, transmit and RF voltage controlled oscillator (VCO) modules and more than 60 other discrete components found in conventional GSM handset designs. This level of integration is an enabling force in simplifying the design and shrinking the form factor of the RF circuitry in GSM voice and data terminals.
The Aero transceiver provides a universal analog baseband interface which is software-programmable and allows designers to implement the Aero RF front end with any supplier's baseband subsystem. It is also compliant with General Packet Radio Services (GPRS) Class 12 and asymmetric EDGE requirements, supporting high data rate communications for Internet-enabled wireless terminals.
A cellular handset has two primary subsystems, RF and baseband. Typically, a different manufacturer supplies each subsystem, requiring the handset designer to choose an RF front-end that is compatible with the preferred baseband subsystem. Silicon Labs' universal baseband interface is programmable via simple software commands enabling it to operate with any baseband solution.
The Aero transceiver can support even the most stringent GPRS requirements. GPRS complements existing cellular technology with high-speed data communications, bringing Internet, email and network connection capabilities to the mobile computing environment. GPRS capabilities are available in most next generation GSM cellular handsets.
