Abstract: A down-frequency conversion circuit and up-frequency conversion circuit, and a receiver and transmitter applying the same are provided. The down-frequency conversion circuit includes a harmonic mixer and general mixer, and thus becomes able to convert frequency using one LO (Local Oscillator) frequency, thereby reducing burden on generating LO frequency.

Abstract translation: 提供了一个低频转换电路和上变频电路，以及一个接收器和发射机应用它。 低频转换电路包括谐波混频器和通用混频器，因此能够使用一个LO（本地振荡器）频率转换频率，从而减少产生LO频率的负担。
