这个主要是用作5GHz以上的频率使用，这个频率以上用作通信的频率少，所以我要求也没有太高。本振的话，因为落在有用频带内，直接不管，因为是噪音源嘛，但是要进行间隔信号的输出，这个就有些问题了。我是以本振...

其实我觉得可以，因为稳态的情况下没有问题的。自举驱动也广泛应用了。但是自举有一个问题，就是瞬态响应不好，比如在频率或者占空比大幅度变化的情况，上管很容易非正常充电进入线性区。这是自举结构的通病，驱动力...

说起氧化环境compatible，一种叫fomblin的特种真空泵油纸面上似乎值得试试，那个东西-100C时粘度也不大，做液氢薄膜喷雾器的时候用过，不过用的地方有加热带，应该没多冷。半开放压进去不用取...
