Abstract:
1. A 4-way power splitter/combiner circuit for use with power amplifiers, comprising: a splitter circuit, further comprising a combiner circuit, further comprising wherein said first amplifier input and said first amplifier output together define a first amplifier port, said second amplifier input and said second amplifier output together define a second amplifier port, said third amplifier input and said third amplifier output together define a third amplifier port, and said fourth amplifier input and said fourth amplifier output together define a fourth amplifier port, each said amplifier port for receiving an amplifier; wherein said first amplifier port, said second amplifier port, said third amplifier port and said fourth amplifier port collectively accept one to four amplifiers and the fraction of power provided to each of said amplifiers is 1/N where N is the number of operative amplifiers; and wherein the phase shift of each of said combiner transmission lines and each of said splitter transmission lines is selected to produce an in-phase signal at said output port.
