Power combiner, power amplifying module having the same, and signal transceiving module

摘要

There are provided a power combiner implemented by a printed circuit board, a power amplifying module having the same, and a signal transceiving module. The power combiner includes: a primary wiring unit formed on one surface of a printed circuit board, receiving a plurality of balance signals having positive balance signals and negative balance signals, and including a plurality of positive primary wirings and a plurality of negative primary wirings, wherein the plurality of positive primary wirings are spaced apart from each other by a predetermined interval, the plurality of negative primary wirings are spaced apart from each other by a predetermined interval, one ends of the plurality of positive primary wirings are connected in common to thereby receive the plurality of positive balance signals, one ends of the plurality of negative primary wirings are connected in common to thereby receive the plurality of negative balance signals, and the other ends of the plurality of positive primary wirings and the other ends of the plurality of negative primary wirings are connected to each other to thereby form a loop; and a secondary wiring unit formed on the other surface of the printed circuit board, and including a secondary wiring combining powers of the plurality of balance signals from the primary wirings forming the loop to thereby output a single end signal.
