摘要
为改善再入遥测系统PCM发射机的性能,首先给出了2MbpsPCM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建模,通过仿真加深了对调频源瞬态特性的理解。其次根据仿真结果来指导实际调试,实验证明非常有效,从而为下一步改善发射机调频源提供了重要参考。
To improve the performance of PCM transmitter, the phase model of 2Mbps PCM transmitter FM source is presented first, also the key elements are modeled with ADS software. It is effective to debug the transmitter circuits with the simulation of FM source modulation response, and it also provides the way to better the transmitter design.
