倍频器
摘要：
本发明公开一种应用于雷达、通讯、量子频标和频稳测量用的自相关倍频器,其特征是,所述倍频器由比较器、延时器、相关器、选频器构成,输入信号经比较器产生一方波信号To,分两路送入相关器,一路直接送入相关器一输入端,另一路经延时器,延时后,输出延时方波信号Tt,Tt送入相关器的另一输入端,在相关器输出端输出一个窄脉冲Tτ,Tτ的脉宽等于延时时间τ,Tτ送入选频器,经选频放大后,输出一个N倍于输入信号Vf的输出信号Vfn,完成倍频。本发明相位噪声低。倍频效率高,电路简单,倍频频段宽,使用方便。
摘要（英）：

An auto-correlation frequency multiplier is composed of comparator, delay unit, correlator and frequency selector. The input signal is fed to the comparator to generate a squarewave signal To, which is sent through two paths to one input end of correlator directly and via delay unit to generate delay square wave signal Tt. Tt is sent to another input end of correl ator to output a narrow pulse Ttau with pulse width equal to delayed time tau. Ttau is fed to frequency selector to output a signal which is N times higher than input signal in frequency. Its advantages are low phase noise, high efficiency, simple circuit and wide bandwidth.
