摘要 利用线性化补偿技术设计了一个位于接收前端T/R组件中的高线性低噪声放大器,通过在常用共源共栅电路中加入线性辅助电路实现。该电路在其他指标基本不变的情况下,线性度提高约15 dB。采用CMOS 0.18μm工艺设计该电路。 One highly linear low noise amplifier in T/R modules adopting the technology of linearization compensation in the front-end of radar receiver was designed, which was realized with the auxiliary circuits from the common cascode circuit.The linearity was improved by 17.5 dBm without sacrificing other fearuers .Simulated with the CMOS 0.18 μm process.
