RF converters enable efficient multiband radios for next-generation wireless base stations

摘要

Ten years after the smartphone revolution, the cellular business is all about data throughput. Single band radios can no longer keep up with the capacity requirements of consumers. To increase data throughput, more spectrum bandwidth must be made accessible through carrier aggregation of multiple bands. RF data converters can access the entire sub-6 GHz cellular spectrum, being quickly reconfigured for various band combinations, making software-defined radio a reality. These frequency-agile, direct RF architectures reduce cost, size, weight and power. This fact has made the RF DAC transmitter and RF ADC DPD receiver the winning architecture of choice for sub-6 GHz, multiband base stations.
