一种高精度RF信号幅相检测电路的设计

A design of high-precision RF signal amplitude and phase detection circuit

本文首先谈论了高精度幅相检测方案的选择,以及带通滤波器的选择和AD8302的主要功能;然后结合f=13.56MH的频率设计了滤波器的参数分析仿真结果;以及AD8302的检测原理的分析。仿真和试验结果证明了这种电路的可行性。

This paper first talk about the high accuracy amplitude and phase detection of programme choice,and the choice of bandpass filter and the primary function of AD8302; then f = 13.56MH with the frequency of the filter design parameters of the simulation results; and AD8302 and the principle of detection, simulation and test results proved the feasibility of such a circuit.
