Texas Instruments high-performance RF transmission signal chain demonstration kit

September 29, 2005, Texas Instruments Inc. (TI) announced a easy to use radio frequency (RF) transmit signal chain demonstration kit, which can reduce the wireless infrastructure (WI) application development time, risk and DS1218 datasheet and cost to significantly speed time to market. Demonstration kit which can provide, including digital baseband and DS1218 price and analog RF transmitter complete RF to meet the wireless base stations and DS1218 suppliers and fixed wireless access equipment, wireless communication standard for all RF transmission needs.

TSW3000 evaluation board (EVM) integrated DAC5687 16 Wei 500 MSPS interpolating digital to analog converter (DAC), CDCM7005 low phase noise and low jitter clock synthesizer and jitter cleaner, TRF3702 ultra-low-noise direct quadrature modulator and the TRF3750 high-performance single-chip phase-locked loop (PLL) frequency synthesizer. Designers can send the Taojian for high-performance front-end chipset, the transmitter in the actual assessment of the various components of performance as a tool confirm that the system can also be used as method of RF signal performance, and no additional work design costs.

The chipset minimizes noise and distortion, and this is the most difficult WI application performance problems. With the TRF3702 phase / quadrature (I / Q) modulator connected, DAC5687s IQ helps to optimize the phase compensation, gain and DC offset to maximize carrier suppression and sideband suppression, while the maximum extent possible to meet power to the modulator. Thus, in the 30.72 MHz frequency for the single-carrier WCDMA applications using 2.14 GHz in the RF local oscillator, we can achieve excellent 71 dB adjacent channel power ratio (ACPR). In the two-carrier WCDMA applications, IF is 92.16 MHz, RF LO to 2.14 GHz ACPR when the chipset is 65 dB. In addition, TSW3000 also in 1.5 GHz to 2.5 GHz frequency range for I / Q modulation. If

design solutions using TSW3000, WI base station manufacturers may need to spend thousands of dollars in costs for parts and other work, the design time for several months to years. In addition, all components are manufactured by TI TI to provide technical support, so those of the demonstration kit as a reference design based on TI offers designers one-stop access to the services to take full advantage of TIs systems expertise and designed for high-speed full range of products, tools and technical support.

TSW3000 is the launch of TI as the base station designers the tools and solutions for new members, and other tools and solutions, including the GC5016 System Evaluation Kit (GC5016SEK) and the TSW1100 data acquisition card and software, the former four-channel broadband for evaluating TI digital frequency down converter, which is used to evaluate the companys high-speed analog-optimized for the WI.

In addition, TI can apply for the wireless infrastructure optimized to provide a powerful set of high-performance low-power digital signal processor. TI is the only company to provide a complete signal chain solutions for semiconductor suppliers, and 10 OEM manufacturers in the 3G base stations, there are nine with TI technology.

Availability
TI has started to provide TSW3000, price is $ 499, including EVM, user guide, software, termination resistors, the components of the data tables, power, and parallel port cable.
