Abstract
An ultra-wideband transceiver includes: one antenna for transmitting a first ultra-wideband signal at time 1 and receiving a second ultra-wideband signal at time 2; a transfer unit that transfers the first ultra-wideband signal from a first node to the antenna or transfers the second ultra-wideband signal received by the antenna to the first node, based on characteristics of an input signal; and a first buffer that generates a first pulse signal for the first ultra-wideband signal and outputs the same to the first node at time 1.
