摘　　要：根据整机小型化需求,设计了一种数字光收发微系统。以系统级封装技术为基础,采用管壳与基板一体化陶瓷针栅阵列封装,对光收发系统所需的各类集成电路裸芯片、光器件和阻容等无源元件进行高密度集成。通过版图设计、信号完整性、电源完整性及热应力仿真,研制出样品。经测试,信号接收SNR大于65 dBFs, SFDR大于86 dBc。模块功能稳定,指标可靠,满足实际需求。According to the requirement of miniaturization, a digital optical transceiver microsystem was designed. Based on system-in-package technology, the integrated ceramic pin grid array package with tube shell and substrate was used to integrate all kinds of components such as bare chips, optical devices and resistance capacitances required by optical transceiver system. Through layout design, signal integrity, power integrity and thermal stress simulation, the sample was developed. After testing, the signal receiving SNR was greater than 65 dBFs, and SFDR was greater than 86 dBc. The module function was stable, and the specification was reliable, which met the actual needs.
