变容调谐二极管朱研变容二极管的出现，在很多方面给电子设计以巨大的推动，尤其是在消费类电子产品中则更是如此。以前用机械方法进行调谐的电路既笨重，又不可靠；采用了变容二极管Ｕ后，在体积、可靠性、调谐速度和跟踪能力等方面都大为改观，诞生了以前所难以企望的体... Variations Tunable Diodes The advent of varactor diodes has in many ways been a huge impetus for electronic design, especially in consumer electronics. The circuit tuned mechanically previously was both bulky and unreliable; with a varactor U, it greatly improved its size, reliability, tuning speed and tracking capabilities, giving birth to previously unimaginable bodies. ..
