NEWPORT BEACH, Calif. -- Conexant Systems Inc. here today announced a low-cost, tri-band power amplifier line designed for handsets based on the Global System for Mobile communications (GSM) and General Packet Radio Service (GPRS) standards.
The new CX77302 power-amp line from Conexant is offered in a low-cost, multi-chip module format, enabling OEMs to save costs and bring their products out in the market more rapidly, said Doug Maki, product manager for the Newport Beach-based company.
The power-amp line is also the company's first tri-band offering, which enables handsets to support the GSM frequency bands in Asia, Europe, and the U.S. markets, Maki said. Previously, it offered a dual-band, power-amp line, which supports the GSM frequency bands in Asia and Europe, he said.
The GSM-based, tri-band digital-cellular market is an emerging market, especially for travelers looking to communicate in a wireless network in Asia, Europe, and the United States, he added.
Overall, the GSM market remains the world's largest digital-cellular standard. The market for GSM phones is projected to grow from 232 million in terms of unit shipments in 2000, to 341 million in 2001, according to estimates from Conexant.
Based on the company's gallium arsenide (GaAs) technology, the power-amp line also supports GPRS, a high-speed wireless-data standard. Supporting the GPRS Class 10 standard, the chip is also optimized to handle three GSM frequency bands: 880- to 915-MHz, 1710- to 1785-MHz, and 1910- to 1950.
The product comes in a module-level format. Measuring 9-by-11-by-1.5 mm, the module consists of a power amp, a current-buffer controller, and 14 passive components. The power amp is based on a GaAs process, while the controller is produced with CMOS technology.
Conexant's CX77302 tri-band GSM power amplifiers are now available for $4.85 each in quantities of 10,000.
