First two-chip system solution for GSM applications introduced by CommQuest.

ENCINITAS, Calif.--(BUSINESS WIRE)--Feb. 18, 1997--

Highly integrated solution provides handset OEMs with low cost,

low power quick-to-market alternative

CommQuest Technologies Inc. has announced the introduction of the first two-chip system solution for wireless voice and data applications that adhere to the Global System for Mobile (GSM) communications standard.

The highly integrated new offering consists of the CQT2110, a single baseband component, and the CQT2030, a single Radio Transceiver IC.

The CQT2110 is available in an advanced 208-pin plastic ball grid array (P-BGA). It is built on CommQuest's proprietary Communications Application Specific Processor (CASP) architecture and its unique one-bit signal sampling technique. The device combines the CASP architecture with audio and RF interface functions.

It implements all of the traditional baseband functions including modulation, demodulation, frame and burst processing, equalization, encryption/decryption, voice coding/decoding, and the mixed signal audio/radio converters and UHF/VHF synthesizers.

The CQT2110 also includes a RISC processor that runs the GSM protocol and user interface software, and contains all interface drivers so no external circuitry other than processor memory is required.

The CQT2030 is a single transceiver IC available in a 48-pin thin quad flat pack (TQFP) package. This component implements an I/Q modulator/up-converter in the transmit path, a one-stage down converter in the receive path, and includes the UHF/VHF voltage controlled oscillators (VCOs). The CQT2030, in conjunction with the CQT2110's analog circuitry, implements all of the radio frequency synthesis functionality. No external synthesizer is required.

"As the first company to offer a two-chip solution for GSM handsets, CommQuest continues to establish itself as a leader in chipset design," said Richard Sfeir, director of strategic marketing for CommQuest Technologies.

"By advancing our chipset package technology even further, we are able to offer our partners many advantages over conventional QFP and PGA packaging. As a result, we help make it easier for handset manufacturers to compete in the GSM marketplace."

CommQuest had announced a three-chip GSM solution last year that is now being sampled by a variety of OEMs throughout the world. The company's GSM offerings are the first to include type-approved GSM protocol software that had previously only been available to cellphone OEMs under expensive licensing arrangements.

CommQuest also offers a comprehensive set of tools in addition to all communication protocol software, a customizable user interface, evaluation boards and a reference design. The result is a low cost, low power solution that allows OEMs to quickly introduce handsets to the market.

Founded in March 1991 and located in Encinitas, CommQuest develops and markets state-of-the-art digital radio system solutions for personal wireless communication markets. Building on its established expertise in the satellite communications industry, CommQuest is now dedicated to meeting the demand for enabling technologies in the burgeoning wireless communications marketplace.

Current products include CommQuest's three-chip GSM system solution, a digital AMPS/TACS three-chip solution, DBS receiver chips, and a wide variety of satellite communications modems.
