Based on a direct-conversion architecture, the receiver integrates LNA, I/Q mixer, DC-offset removal filter, baseband amplifier and channel-select filters on a single chip.
基于直接下变频的系统架构，接收机集成了低噪声放大器、I/Q下变频器、去直流偏移滤波器、基带放大器和信道选择滤波器。
Then, the analysis in theory and the designing method of the key parts in the system, such as SPDT switch, LNA, AGC and filter, is carried out. Finally, the function of each part is tested.
然后对其系统中的关键组成部分，SPDT开关、LNA、AGC、滤波器进行了理论和设计方法上的分析，最后对其各部分进行了实验和测试。
