RF All-In-One
Posted date : Oct 31, 2007

IBM’s new CMOS 7RF SOI technology offers significant cost advantages to designers of mobile handsets.

For mobile phones, laptops and other portable communication devices to reach a broad user base in emerging markets, designers need affordable, power-efficient and high-performance solutions that will further reduce the complexity of components.

To that end, IBM has recently introduced CMOS 7RF SOI technology for our foundry customers. It is designed to enable singlechip RF solutions by integrating the multiple RF/analog functions of today’s handsets – such as multi-mode/multi-band RF switches, complex switch biasing networks, and power controllers – into single-chip solutions for mobile devices.

This new technology provides an integration pathway, enabling designers to integrate filter, power amplifier, power management and receiver/transmitter functions. The breakthrough technology in SOI can minimize insertion loss and maximize isolation to help avoid issues such as loss of signal or dropped calls, potentially enabling significant cost advantages to mobile handsets.

The 180-nm CMOS 7RF SOI is tailored for RF switch applications that provide a low-cost alternative to solutions based on gallium arsenide (GaAs). Initial hardware evaluations have been completed; general availability for design kits is planned for the first half of 2008.
