PIN調制器用于線性脈沖調制的可能性
POSSIBILITY OF USING THE PIN MODULATOR FOR LINEAR PULSE MODULATION
-
摘要: 本文分析了PIN調制器的電流調制特性,對其在線性坐標上呈現(xiàn)的高度非線性作了討論,并進一步提出了采用對數網絡使其線性化的電路補償方法,這種方法在實驗中已獲得成功。

Abstract: The current modulation characteristic of PIN modulator is analyzed, and its highly-nonlinear characteristic appearing on a linear coordinate is discussed. A circuit com-pensation method, in which a logarithmic network is mainly used, is presented for making the modulator linearized. This method shows up satisfactorily in experiment. -
