摘　　要：A 2.4 GHz, direct-conversion RF transmitter front-end with an up converter and PA driver is fabricated in a 0.13/zm CMOS process for the reliable transmission of 54 Mb/s OFDM signals. The front-end output power is -3 dBm while the corresponding EVM is -27 dB which is necessary for the 802.11g standard of EVM at-25 dB. With the adopted gain control strategy the output power changes from -14.3 to -3.7 dBm with every step 0.8 dB （20%） which covers the gain variation due to working temperature and process. A power detector indicates the output power and delivers a voltage to the baseband to control the output power.A 2.4 GHz, direct-conversion RF transmitter front-end with an up converter and PA driver is fabricated in a 0.13/zm CMOS process for the reliable transmission of 54 Mb/s OFDM signals.
