Power coupler, a power amplifier module with a power coupler and signal transmission module

摘要

It is a power coupler is described, which by means of a printed circuit board, a power amplifying module, which has the printed circuit board, and a signal transmission module is formed. The output coupler includes: a primary wiring unit, on an upper side of the printed circuit board is formed and a plurality of symmetrical receives signals, the positive symmetrical signals and negative symmetrical signals, and further comprising a plurality of positive primary wiring and a plurality of negative primary wirings, wherein the plurality of positive primary wiring in a fixed distance from one another are spaced apart from the plurality of negative primary wirings are spaced apart from one another in a fixed distance, one end of the plurality of positive primary wiring is connected in common, in order thus to make the more positive symmetrical to receive signals, one end of the more negative primary wiring is connected in common, in order thus to make the more negative symmetrical to receive signals, and the other end of the plurality of positive primary wiring and the other end of the more negative primary wirings are connected to one another, in order thereby to form a loop; as well as comprising a secondary wiring unit, which is located on the other upper side of the printed circuit board is formed, and comprising a secondary wiring, which the outputs of the plurality of symmetrical signals of the primary wiring, which form the loop, and combines, in order thereby to output a single end signal.
