초록
In this paper, we design RF transceiver architecture and building blocks for impulse radio UWB system. Impulse radio UWB signal occupies the wide frequency band which is very low transmission power. So, it can minimize the interference effect with the other system. Using UWB technology, we obtain position awareness service. Therefore, we describe the RF transceiver architecture of direct conversion receiver and define the requirement of RF transceiver. Moreover, we implement a prototype RF transceiver based on the presented standard and verify a function and performance through the wireless data communication and ranging test.
