Analog Devices Delivers Breakthrough Radio Frequency Circuits for 4G Cellular Base Stations

Source: Analog Devices press release
Analog Devices, Inc., a global leader in high-performance semiconductors for signal-processing applications and RF integrated circuits, today introduced a series of highly integrated RFICs (radio frequency integrated circuits) designed for LTE (long term evolution) and 4th generation (4G) cellular base stations. LTE is a set of enhancements to the UMTS (universal mobile telecommunications system) standard and is considered to be the last step toward the 4th generation of radio technologies in cellular networks. As worldwide mobile carriers evolve toward 4G technologies, small higher-density radio card form factors are needed to support the delivery of continuous voice and high-data-rate services. ADI’s new ADRF660x series of mixers and ADRF670x series of modulators enable these high-density radio cards by combining multiple discrete functional blocks into a single device, while meeting the demanding performance required by higher-capacity base stations. With this breakthrough level of integration, base station manufacturers can realize an unprecedented 60 percent reduction in board space and a significant savings on bill of materials costs.
