混合的频率和阶段锁住系统被设计,在哪个电磁的防护,联合的微波,和中间的频率(如果) 测量安排被包括。代替液体氮,一个脉搏试管 cryo 冷却器被用来使整个系统凉下来。与是的 Josephson 谷物边界连接混合元素,在 3 公里波浪乐队混合的第 96 泛音频率被获得,并且锁阶段的控制电压的振荡器(VCO ) 被认识到。
A frequency mixing and phase locking system is designed, in which electromagnetic shielding, microwave coupling, and intermediate frequency (IF) measurement arrangements are included. In lieu of liquid nitrogen, a pulse tube cryocooler is used to cool the whole system. With Josephson grain boundary junction as the mixing element, the 96th harmonic frequency mixing at 3 mm waveband is obtained, and phase-locked voltagecontrolled oscillator (VCO) is realized.
