Texas Instruments Inc. has added three release-to-production RF transceiver reference designsthe TSW5002/3/5to its portfolio of wireless signal chain solutions for WiMAX applications.

The new 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.

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

The TSW5005 reference design, operating at 5.6GHz, incorporates the TRF2432 and TRF2436 heterodyne transceiver two-chip chipset. These chipsets support 4.9-5.9GHz 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 2.3-2.7GHz, 3.3-3.8GHz and 4.9-5.8GHz, respectively. Designers can customize the design by substituting on-board filters centered at its band of interest.

All three reference designs will be available via online order entry in Q4 2006 at an evaluation module (EVM) price of $499 for each of the three boards.
