Method of processing RF signal and RF receiver

The embodiment of the invention provides a method for processing a radio frequency (RF) signal and an RF receiver, and the method for processing the RF signal comprises the steps: amplifying the RF signal; digitizing an RF signal with a delta-sigma analog-to-digital converter in the RF domain, where digitizing the RF signal comprises: filtering the RF signal with an n-order resonant band-pass filter, where ngt; 1; sampling the filtered RF signal in the ith Nyquist region, wherein igt; 1; and generating a digital in-phase signal and a digital quadrature signal according to the sampled signal. By using the technical scheme, the RF receiver has relatively good noise immunity and relatively low power consumption. 本发明实施例提供一种处理RF信号的方法和RF接收器，其中，处理射频RF信号的方法包括放大RF信号；在RF域中利用Δ-Σ模数转换器对RF信号数字化，其中对所述RF信号数字化包括：用n阶谐振带通滤波器对所述RF信号滤波，其中n>1；在第i个奈奎斯特区域对滤波后的RF信号采样，其中i>1；以及根据采样后的信号，产生数字的同相信号和正交信号。使用该技术方案，可以使得RF接收器具有较好的抗噪性且具有较低的功耗。
