TI Unveils Single-Chip Direct Conversion Radio Frequency Solution for GSM-, GPRS- and UMTS-Based Wireless Standards
Highly Integrated, Multi-Band Device Reduces Wireless Handset Component Costs by 1/3 and Shrinks Board Size by More than 15 percent
DALLAS, Feb. 5 /PRNewswire/ -- Extending its portfolio of wireless solutions for 2.5 and 3G wireless handsets and advanced mobile computing devices, Texas Instruments Incorporated (TI) (NYSE: TXN - news) today unveiled a single-chip direct conversion radio frequency (RF) solution for the Universal Mobile Telecommunications System (UMTS), General Packet Radio System (GPRS) and Global System for Mobile (GSM)-based wireless telephone handsets. TI's new highly integrated RF solution will enable wireless handset original equipment manufacturers (OEMs) to build smaller systems with fewer components at a lower cost than competing solutions.
The new TRF6150 direct-conversion RF device reduces the overall RF bill of materials (BOM) by 15 percent over other announced direct-conversion devices, and by 30 percent over solutions currently in production. The device also enables a 15 percent reduction in required board space. At the same time, the TRF6150 provides enhanced functionality over competing devices and has demonstrated signal quality better or equivalent to today's RF solutions.
``Direct-conversion radios are the wave of the future for GSM handsets. Texas Instruments' TRF6150 is riding the crest of that wave. With its small footprint, small number of external components, and surprisingly low price, the TRF6150 will make possible the production of smaller, lighter, and less expensive GSM and dual-mode UMTS/GSM telephones,'' said Jack Quinn, President, Micrologic Research.
Leveraging TI's wireless system and integration expertise, TRF6150 offers the most comprehensive single-chip RF solution for GSM handsets on the market today. The device integrates a power amplifier controller and on-chip low-dropout (LDO) regulators, while requiring only two external filters with a single external voltage control oscillator (VCO). As a result of this advanced integration, these and other on-chip features enable the design of a dual-band GSM RF section with an area below 10 square centimeters (cm2) on a single-sided printed circuit board (PCB).
``Only TI delivers the critical ingredients to enable the highest performance, lowest power solutions for 2, 2.5 and 3G handheld communications environment, including the analog, programmable DSP-based digital baseband, RF and power management,'' said Gilles Delfassy, Senior Vice President, TI's Wireless Communications Unit. ``TI's single-chip direct conversion RF solution is just another extension of our proven ability to bring leadership technology to the entire handset.''
The TRF6150 also provides implementation flexibility and ease of design for wireless handset OEMs. Serving as a single-chip dual- or tri-band transceiver, the device is compliant with the GSM version 2.5 and GPRS class 12 industry standards and is also compatible with UMTS requirements. Hence, its frequency plan is compatible with the implementation of TI's Bluetooth and Global Positioning System (GPS) technologies in the same handset. The device is matched to all of TI's available analog baseband solutions for GSM, minimizing the need for system tuning. To speed system design, TI offers a PCB reference design for RF sections based on the TRF6150.
Direct-conversion RF reception, a recent introduction to wireless handset design, eliminates the bulky and expensive filtering associated with intermediate frequencies in traditional schemes. Combined with VCO integration, direct conversion allows a significant system cost reduction. In addition, the breadth of TI technology enables the TRF6150 to work seamlessly with the analog and digital baseband sections of the phone.
``TI's testing of TRF6150 samples against the most stringent GSM conditions demonstrates that the company has mastered the technical challenges of direct conversion and VCO integration in a highly integrated device,'' said Pascal Lemasson, GSM/UMTS Product Marketing Manager. ``TI's advanced RFBiCMOS-II(TM) process, featuring a high 25-GHz transition frequency (fT), is among the industry's top-performing processes of its class. Based on this process, TRF6150 is better or equivalent to traditional superheterodyne solutions in RF reception, while reducing board space by one-fourth, component counts by one-third and costs by one-third over these solutions.'' TRF6150 and its PCB reference design are available in sample quantities today, with volume production of the device scheduled for the second quarter of 2001. The TRF6150 is packaged in a 64-lead thin quad flatpack (TQFP). Planned pricing is $5 each in quantities of 10k.
