摘　　要：发射机的调制性能关系到发射机设计的成败与否。首先给出了基于PLL的发射机调频源的相位模型,并在ADS环境中进行了关键器件的线性建模,通过ADS仿真加深了对其瞬态特性的理解。其次根据仿真结果来指导实际调试,取得满意的效果。Modulation performance of the transmitter relates to whether the design of the transmitter is successful. First, phase model based on the PLL of FM source of the transmitter has been produced, and the linear model of the key components has been carried on in the ADS environment; and deep- ened the understanding of its characteristic of transient state by emulating the ADS. Secondly, we obtains satisfactory results as we guide the actual debugging according to the emulation results.
