本文证实了一种使用兰姆(Lamb)波压控振荡器的频率调制器.该兰姆波器件采用三个叉指换能器,须经过作为压控电阻器的FET(场效应晶体管)馈送调制信号给器件中部的换能器,其余的两个换能器与一个放大器组成延迟线振荡器.振荡频率依加于FET上的电压线性地变化.叙述了该器件的设计和基本特性. This paper demonstrates a frequency modulator using a Lamb wave voltage controlled oscillator that uses three interdigital transducers and is fed via a FET (Field Effect Transistor) as a voltage-controlled resistor Modulating the signal to the transducers in the middle of the device, the remaining two transducers and an amplifier form the delay line oscillator, which oscillates linearly with the voltage applied to the FET, describing the design and basic characteristics of the device.
