Sampling phase detector
专利汇可以提供Sampling phase detector专利检索，专利查询，专利分析的服务。并且PURPOSE:To offer a sampling phase detector with high detecting sensitivity by using a gallium-arsenic field effect transistor (TR) as a switching element. CONSTITUTION:A low-frequency signal, e.g., 100MHz applied to a terminal 15 is fed to a step recovery diode 3 through a coil 8, the signal is converted into a narrow pulse train, the low-frequency component is eliminated by a capacitor 11 and the result is fed to the gate of the gallium-arsenic field effect TR12. On the other hand, an ultrahigh frequency signal voltage applied to the drain of the gallium-arsenic field effect TR12 from a terminal 16 is changed depending on ON/OFF of the gallium-arsenic field effect TR12. Although the extracted signal part is shifted when the phase of the ultrahigh frequency signal and the harmonic of the low-frequency signal is not coincident, the signal is integrated by a capacitor 13 and the relation becomes the same as the comparison of the harmonic component of the low-frequency signal and the ultrahigh frequency signal.，下面是Sampling phase detector专利的具体信息内容。
