TI Introduces RF Transceiver Reference Designs For WiMAX Applications

Boston -- Texas Instruments Incorporated (TI) expanded its portfolio of complete wireless signal chain solutions for WiMAX applications, introducing three release-to-production radio frequency transceiver reference designs. These designs support IEEE's 802.16d/e standard RF front end requirements for a variety of wireless infrastructure technologies, including base stations, access points, wireless backhaul, point-to-point microwave, safety band and Frequency Division Duplex (FDD)-based applications. The complete reference designs include board, design database, schematics and bill of materials to significantly reduce development time. TI is currently displaying these reference boards in its booth number 525 at WiMAX World, October 10-12, at the Boston World Trade Center.

"Axxcelera is one of the world's most experienced wireless solutions providers, and to maintain our leadership, we need to quickly roll out high-performance WiMAX products to meet industry demand," said Tony Masters, senior vice president of Engineering and Operations at Axxcelera. "TI's complete WiMAX reference designs enable us to maintain our high level of performance and reliability and still deliver products to the market as quickly as possible."

The TSW5002 RF reference design, which operates at 2.5 GHz, incorporates TI's TRF11xx chipset and the TSW5003, operating at 3.5 GHz, utilizes the TRF12xx chipset. Both chipsets consist of five chips with fully integrated superheterodyne receivers and transmitters. These complete reference designs support FDD, Half Frequency Division Duplex (HFDD) and Time Division Duplex (TDD) modes with a real interface at a low intermediate frequency (IF) to the data conversion subsystem. TI's RF chipsets are compliant with today's mask requirements, while the receivers feature sensitivity and blocker suppression.

The TSW5005 reference design, operating at 5.6 GHz, incorporates the TRF2432 and TRF2436 heterodyne transceiver two-chip chipset. These chipsets support 4.9 to 5.9GHz air interface frequency band, and consist of an IF and RF transceiver. The reference design supports TDD mode with complex I/Q interface.

In addition to providing a complete design for the designated frequency, each reference board can be customized for the various transceiving frequencies supported by each chipset. The TSW5002/3/5 can be customized for frequency ranges of 2.3 to 2.7 GHz, 3.3 to 3.8 GHz and 4.9 to 5.8 GHz respectively. Designers can customize the design by substituting on-board filters centered at its band of interest.

"TI is committed to the WiMAX industry and wants our customers to benefit from our years of experience in developing the industry's best RF solutions, allowing them to meet emerging market requirements in the shortest timeframe to speed their market entry," said David Briggs, manager of TI's analog wireless infrastructure products. "Our complete, advanced RF reference designs also offer manufacturers a lower bill of materials for a fully tested RF transceiver, ready to be implemented into WiMAX-compliant designs immediately."

In addition to providing analog products for the WiMAX market, TI also delivers DSPs, and a Wave 1 certified software library. TI provides the complete signal chain solution for WiMAX infrastructure applications.
