摘要
声光可调谐滤波器的设计,关键是它的各个模块,包括光波导、模分离器、声波导和叉指换能器的参数设计。设计了叉指换能器各个参数,并对其射频驱动电路和匹配电路给出了设计思路,其中电路控制系统以单片机AT89C52为主控制器,在频率为158 MHz频谱仪上得出了频率合成器的测试结果。
The parameter design of every module including optical waveguide, mode splitter, acoustic waveguide and interdigital transducer is the key to the design of acoustic-optical tunable filter. The parameters of interdigital transducer are designed, and the design ideas of radio frequency drive circuit and matching circuit are put forward. Taking micro controller unit （MCU） AT89C52 as the master controller in circuit control system, the test result is obtained by a 158 MHz frequency synthesizer.
