Abstract
An RF front-end circuit in a receiver, comprising a low noise amplifier (LNA) configured to receive an RF signal from an antenna; a frequency synthesizer and divider (FS_DIV), configured to generate a first local oscillation (LO) signal, a second LO signal, a third LO signal and a fourth LO signal; a first front-end circuit communicatively coupled to the LNA and the FS_DIV, and configured to output a first digital intermediate-frequency signal by processing the amplified RF signal and the first LO signal and a second digital intermediate-frequency signal by processing the amplified RF signal, the first and second LO signals; a second front-end circuit communicatively coupled to the LNA and the FS_DIV, and configured to output a third digital intermediate-frequency signal by processing the amplified RF signal and the third LO signal and a fourth digital intermediate-frequency signal by processing the amplified RF signal, the third and fourth LO signals.
