【英文摘要】Wireless munication is a kind of munication manner which can exchange information using electromagnetic waves that propagate in free space. In recent years, the development of the wireless munication technology has made the correspondence among people bee more convenient, and its application is more and more this thesis, a study is performed about the High frequency wireless transceiver, has produced this design detailed process and the final realization electric circuit, and the electric circuit principle of work is deeply studied. First of all, this paper gives a theoretical analysis of the modem, power amplifier, crystal oscillator, mixers and detectors and designs the corresponding circuit of each module based on the results of analysis of principles. Then PSPICE is used to simulate the circuit to optimize the circuit, according to the results of simulation make the circuit wor
