Abstract:
1. A wireless communication system, comprising: a transceiver having a transmitting end and a receiving end; a first filter unit coupled to the transmitting end for filtering a radio frequency signal sent out from the transceiver and generating a first processed signal; a second filter unit coupled to the first filter unit for filtering the first processed signal and generating a second processed signal; and a first amplifying unit coupled to the second filter unit for amplifying the second processed signal to generate a third processed signal, wherein the first filter unit is a harmonic oscillation circuit that comprises an inductive component and a capacitive component, and the inductive component and the capacitive component are serially coupled, and wherein one end of the inductive component is coupled with the transmitting end and an input end of the second filter unit, the other end of the inductive component is coupled with one end of the capacitive component, and the other end of the capacitive component is grounded.
