Abstract
One embodiment of the present invention provides a remote radio head (RRH) for a wireless communication system. The RRH includes a first integrated circuit (IC) chip that comprises multiple functional blocks, a second IC chip that comprises at least a frequency up-converter for up-converting outputs of the DAC block to a radio frequency (RF) domain and a frequency down-converter for down-converting RF signals received from one or more antennas, and a plurality of RF front-end components that are packaged into a system in a package (SiP) module. The multiple functional blocks in the first IC chip include at least a processing unit, a digital-to-analog converter (DAC) block, and an analog-to-digital converter (ADC) block.
