本文介绍一种稳定的毫米波雪崩二极管振荡器。如果从二极管位置所观察的振荡器的负载阻抗的实部和虚部能够容易独立地变化的话,那么振荡器便能在毫米波频段的任一频率产生最大的输出功率。振荡器的形伏和尺寸是根据一个放大五倍的比例模型测量确定的。这种振荡器能在40～60千兆赫的宽频率范围获到20分贝毫瓦或更大的功率,用相同的二极管在75千兆赫能获得15分贝毫瓦以上的输出功率。 This article describes a stable millimeter-wave avalanche diode oscillator. If the real and imaginary parts of the load impedance of the oscillator as viewed from the diode location can easily and independently vary, then the oscillator can produce maximum output power at any frequency in the millimeter wave band. The shape and size of the oscillator are based on a five-fold magnification model measurement. This oscillator achieves a power of 20 dBm or more over a wide frequency range of 40-60 GHz, with the same diode delivering output power of 15 dBm or more over 75 GHz.
