Silicon Labs rolls integrated transceiver

Silicon Laboratories Inc. has started sampling a single-chip transceiver, the Aero II, that executives said reduces the BoMs required for quad-band GSM cellular handsets.

Created in a CMOS 130nm process, the Aero II is the company's third generation Aero transceiver, a product family that has accounted for much of the growth of Silicon Laboratories, now a roughly $500 million company in terms of annual sales.

The Aero II reduces the size of a quad-band transceiver module to a 5-by-5 mm package containing five components, matching the transceiver with a crystal, a SAW filter bank and two standard bypass capacitors. An external power amplifier and an antenna switch are the only other devices required to complete the RF function.

The device integrates the RF and IF voltage-controlled oscillators (VCOs), VCO tuning components, loop filters and clock coupling capacitors. The transceiver supports the use of a VC-TCXO module, as well as the integration of a digitally-controlled crystal oscillator that enables the use of a standard 26MHz crystal to provide the transceiver reference clock.

Ed Healy, VP of Austin-based Silicon Labs, said the transceiver simplifies the design process, reduces the BoMs and improves the receive and transmit path performance compared with the company's previous transceiver products. The Aero II "is a fundamental building block that will support customers as they plan their Edge offerings," Healy said.

The Aero II is priced at $4.94 in quantities of 10,000, and is sampling now.
