摘要： The invention generally relates to a radio frequency (RF) chip and/or a baseband chip for use in a wireless transmitter and/or receiver. Embodiments of the invention solve a problem caused by a mismatch in amplitude and/or phase between in-phase (I) and quadrature (Q) signals in such communication devices. According to an aspect of the invention, there is provided a communication device including: a baseband signal processing unit configured to output a plurality of analog baseband signals through a corresponding plurality of channels; and a radio frequency (RF) processing unit coupled to the plurality of channels, the RF processing unit configured to convert the plurality of analog baseband signals into a plurality of digital signals using a shared analog-to-digital converter (ADC), the RF processing unit further configured to generate an RF signal based on the plurality of digital signals.
