基于ADS的多通道下变频器仿真设计

Design and Simulation of Multi-Channel Down-Converter Based on ADS

重点讨论L波段多通道下变频器的设计与仿真。采用自上向下的方法,以Agilent ADS软件为平台建立仿真模型,选用S参数和谐波平衡仿真工具对多通道下变频器信道进行设计仿真,经过优化得到低噪声、高动态的仿真指标,实现多通道变频方案的可行性论证。

This paper focuses on the design and simulation of L band multi-channel down-converter.The simulation model is built up on the Agilent ADS software platform by the method of top-down.It is designed by the S-parameter and harmonic balanced simulation.The low noise and high dynamic range simulation results can be achieved by the optimistic method.And the feasibility of the multi-channel converter design is demonstrated.
