초록
In this paper, a down-converter that can work for L-band RF front-end of DMB receiver is designed. Since DRK-02, a reference for our work, had been designed for a stationary receiver, not for mobile one, the supply voltage is set relatively high of 8.5V. We improve it with 3.3V and save design space and cost by employing only one Mixer and IF_Amp comparing to the reference one in which two Mixers and two IF_Amps are used.
