Abstract :
An RF Transmitter front-end implemented in 0.18 μm CMOS for WiMedia MB-OFDM UWB is presented in the paper, which consists of a V-I converter, an up modulator, a Differential to Single (D2S) converter, a PA and the divided by 2 divider for the LO carrier generation. The post simulation shows the maximum transmitter linear output power level of -2 dBm (3.1-4.8 GHz band) with 6 dB power control range, output P1 dB over 0 dBm, 44 dBc image rejection ratio and the core chip current consumption is only 24 mA with 1.8 V supply voltage for the complete RF transmitter front-end.
