Abstract:
Provided are a radio-frequency integrated chip (RFIC) and a wireless communication device including the RFIC. An RFIC configured to receive a carrier aggregated receive signal having at least first and second carrier signals may include first and second carrier receivers configured to generate, from the receive signal, first and second digital carrier signals, respectively. A phase-locked loop (PLL) may output a first frequency signal having a first frequency to the first carrier receiver and the second carrier receiver. The first and second carrier receivers may include first and second analog mixers, respectively, for translating frequencies of the receive signal, using the first frequency signal and the second frequency signal, respectively. Each of the first and second carrier receivers may further include a digital mixer for farther translating the frequencies of the receive signal in the digital domain.
