摘要: A hybrid amplifier for connecting a signal carrying line to a repeater. The hybrid includes an autotransformer having a center tap dividing it into two portions. The signal carrying line, an amplifier section, a terminating resistor, and a feedback network are connected to the autotransformer in such a manner that the signal carrying line and the feedback network form a first conjugate pair and the amplifier section and the terminating resistor form a second conjugate pair.
