摘要
在射频系统中,混频器可以将较高频率的输入信号变换为较低频率的输出信号,以便对信号进行后续的调整和处理,一般通过混频二极管实现频率的变换。文章主要采用ADS软件对接收电路中的混频部分进行性能上的优化设计,运用软件的HARMONIC BALANCE仿真器中的参数扫描(Sweep)功能和扫描控制器进行仿真,得到三阶交调图和最理想的本振功率。通过ADS对射频混频器的仿真,得到了混频器的一些重要性能指标,大大提高了设计效率,缩短设计周期,并对混频器的参数进一步优化,提高了混频器性能。
The RF system, The mixer can transform the high frequency input signal into lower frequency output signal, In order to more easily to adjust and process signal. Usually by frequency mixing diode to transform frequency, this paper mainly use the ADS software to perform the mixing part of receiving circuit, Using the Scan （Sweep） function parameters of the HARMONIC and scanning controller to simulation, get the first three into the figure and the most ideal vibration power, improve the design efficiency greatly, shorten the design cycle, and the parameters of the mixer further optimization to imt^rove the. miY^r n^rf,~rm
