Abstract

The proposed MB-OFDM UWB transmitter system, which is implemented in 0.13 mu CMOS technology, consists of a LPF, a VGA, a V-I converter, an up-mixer, and a driver amplifier. Measured results show maximum transmitted output power level of -10 dBm, output P1dB of -7 dBm, and bandwidth of more than 250 MHz and gain flatness of less than 1 dB for all three sub-bands. The implemented transmitter can transmit 4-HD channel simultaneously, so that make wireless links between multimedia devices demanding high data rate.
