Lime Microsystems has announced the availability of the LMS6002D, a multi-band, multi-standard RF transceiver IC designed for small cellular base stations and femtocells, featuring integrated, high-performance, dual ADC and DAC. This single-chip transceiver solution delivers increased levels of integration over the company's analogue version, the LMS6002. The highly frequency-agile transceiver is suitable for 3G, WiMAX, and LTE operation. The new transceiver can be digitally configured to operate in the full range of frequency bands between 375MHz and 4GHz, with 16 user-selectable bandwidths of up to 28MHz. It can therefore transmit and receive data across all WCDMA and CDMA bands, as well as those used or planned for WiMAX and LTE. This removes the need for individual transceiver chips for each of the different bands, and allows a small cell base station to be reconfigured rapidly. The 12bit ADC and DAC blocks provide the necessary multiplexed parallel interface to all baseband ICs for femtocell applications. The IC is available in a 9x9mm 116pin DQFN package.
