1. one kind is used for the baseband portion (BBIC) of interface wireless electricity transmitter and the circuit of radio (TXIC), comprising:

  • Said radio (TXIC) locate from said baseband portion (BBIC) receive a current signal ('"'"' going into '"'"') receiving system (I, Q, Ibar, Qbar), said current signal ('"'"' going into '"'"') has at least two components that separate through physical circuit;

    WithDistributor (PA, PB, PC, PD;

    PE), be used for from receiving system (I, Q;

    Ibar Qbar) receives said current signal ('"'"' going into '"'"'), and at least two components in the said current signal ('"'"' going into '"'"') each is carried out shunt;

    And between the path that comprises the component in the current signal identical of a plurality of mixers path (105,107), utilize the Parallel coupled transistor with a plurality of processing of dummy load path (103);

    Optionally and concomitantly distribute each of component in the current signal after this shunt, so that the electric current of the component in the current signal of the different proportion after will this shunt is directed to different load circuitsWherein, said distributor has at least two mixers, is used for the electric current of the component of the current signal different proportion after the shunt, that flow through the mixer path is carried out mixing;

    Wherein, the distribution of the current signal after this shunt was carried out before utilizing the carrier signal modulation.
