OTHELLO DIRECT CONVERSION RADIO

The Othello direct conversion radio chipset has been designed to be incorporated into GSM/GPRS cell phones and wireless Internet devices. The Othello One integrates all of the functionality of the first-generation Othello radio chipset into a single chip, providing further reductions in size and materials. The chipset offers a 40% reduction in total component count from its previous generation and other direct conversion implementations, which translates into significant cost savings. In addition, the device addresses emerging GSM derivative standards such as EDGE (enhanced data for GSM evolution) and GPRS (general packet radio service).

Introduced in September 1999, Othello was the first open-market direct conversion radio chipset. This technology simplifies traditional radio architecture by allowing incoming signals to be converted directly to baseband and eliminates the need for intermediate frequency surface acoustic wave (SAW) filters. The Othello RF architecture also offers numerous manufacturer and end-user benefits including support for voice and data throughput rates up to 384 kbps, 1000 h of standby time, and 25% reduction in the size of the radio section of a cell phone. A reference design using Othello One fits on a PCB measuring 3 ý 5 cm (about 1.25ý ý 2ý), with the radio section occupying only 7 cmý. In addition, Othello One enables dual- and tri-band GSM cell phone manufacturers to upgrade easily and adapt their products to multi-mode and multi-slot data applications.

Pricing for Othello One is not yet available.
