Side-feeding radio-frequency amplifier

一种侧馈送RF放大器，它包括数个并联的晶体管，使每个晶体管的基极，发射极和集电极的引脚分别与其它所有晶体管的基极，发射极和集电极的引脚电连接。一个公共物理点将功率放大器的电流源和每个晶体管的基极引脚互连。晶体管在功率放大器中设置成公共物理点和任一晶体管基极引脚之间的阻抗大致与公共点和其它任一晶体管基极引脚之间的阻抗相等。 A side fed RF amplifier comprising a plurality of transistors connected in parallel such that the base, emitter, and collector leads of each transistor are electrically connected to the base, emitter, and collector leads, respectively, of all other transistors. A common, physical point interconnects the power amplifier current source and the base leads of every transistor. The transistors are arranged such that the impedance between the common physical point and the base lead of any one transistor is substantially equivalent to the impedance between the common point and the base lead of any other transistor within the power amplifier.
