当卫星多个波段信标信号穿越电离层传播时，电离层会产生时延、闪烁等效应。精确测量这些效应需要设计高精度的接收机，而接收机的开发关键的工作是合理设计接收机射频前端。基于卫星信标信号接收机的设计，提出了一种多波段接收机射频前端的设计方案，进行了仿真实现，并给出了初步的观测结果。%The satellite multi‐band beacon signals are prone to the delay and scintillation effects when transmitting through the ionosphere .The design of the receiver is needed to measure these effects preciously .The most important ,for designing the receiver ,is the de‐sign of RF frond‐end .T he design and simulation of the multi‐band RF front‐end are presen‐ted ,and the primary results are also given .
