    • A high frequency second harmonic oscillator includes a transistor, a first signal line connected at a first end to the base or gate of the transistor, a first shunt capacitor connected at a first end to a second end of the first signal line and at a second end to ground, a second signal line connected at a first end to the collector or drain of the transistor, a second shunt capacitor connected at a first end to a second end of the second signal line and at a second end to ground, and a high capacitance capacitor connected between the first signal line and the second signal line. The first signal line has a length equal to an odd integer multiple of one quarter of the wavelength of a fundamental signal, plus or minus one-sixteenth of the wavelength of the fundamental signal.
    • 高频二次谐波振荡器包括晶体管,在第一端连接到晶体管的基极或栅极的第一信号线,在第一端连接到第一信号线的第二端的第一并联电容器, 在第一端连接到晶体管的集电极或漏极的第二信号线,在第一端连接到第二信号线的第二端并在第二端连接到地的第二并联电容器,以及 连接在第一信号线和第二信号线之间的高容量电容器。 第一信号线具有等于基本信号波长四分之一的奇整数倍的长度,加上或减去基波信号波长的十六分之一。
