发射部分采用锁相环式频率合成器技术， MC145152和MC12022芯片组成锁相环，将载波频率精确锁定在35MHz，输出载波的稳定度达到4×10-5，准确度达到3×10-5，由变容二极管V149和集成压控振荡器芯片MC1648实现对载波的调频调制；末级功放选用三极管2SC1970，使其工作在丙类放大状态，提高了放大器的效率，输出功率达到设计要求。,Part of the launch phase-locked loop frequency synthesizer using technolog

C语言实现了数字锁相环的程序，不过程序比较复杂，得参照MATLAB中 Discrete 3-phase pll模型,C language implementation of the DPLL procedure, but more complicated procedures, may refer to MATLAB, Discrete 3-phase pll model
