Distributed balance frequency multiplier

摘要

A distributed balance frequency multiplier has a transmission line that is configured using lumped elements having connection points for inputting signals. Connected to each connection point is the output from a non-inverting amplifier which does not invert a signal applied thereto. A second transmission line is configured also using lumped element techniques and has connection points for receiving an inverted amplified signal whose odd harmonics are 180 DEG to the non-inverting amplified signals. The signal that is to be amplified is carried to both the non-inverting and the inverting amplifier by a third transmission line that also uses lumped elements distribution techniques to create a transmission line. The output of the first transmission line and the second transmission lines are tied together so that the odd harmonics due to the inverting amplification stages cancel and the even harmonics are additive, thereby achieving an effective multiplication of the input signal.
