New Device Enables Direct RF to Baseband Signal Conversion in 3G Base Stations 

US : Expanding its broad portfolio of analog and digital signal processing products for wireless infrastructure base station manufacturers, Texas Instruments introduced a new monolithic, high-linearity ... quadrature demodulator for direct down conversion applications. The new device reduces the component count of the receive signal chain in 3G base stations by at least 75 percent, compared to superheterodyne architectures. The TRF3710 demodulator improves the RF receive signal chain by integrating all the devices required to go directly from RF to baseband onto one chip. With the addition of this device, TI now offers a more complete analog signal chain for wireless infrastructure. Highest Level of Integration with Excellent RF Performance The TRF3710 is optimized for use in direct down-conversion architectures where space and cost savings are key requirements. It is the first RF device in the industry to integrate a baseband filter that is software-programmable with 1-dB corner freque   [More...] [Less...]
