%X A 2.4GHz CMOS monolithic transceiver front-end for IEEE 802.11b wireless LAN applications is presented.The receiver and transmitter are both of superheterodyne structure for good system performance.The front-end consists of five blocks:low noise amplifier,down-converter,up-converter, pre-amplifier,and LO buffer.Their input/output impedance are all on-chip matched to 50Ω except the down-converter which has open-drain outputs.The transceiver RF front-end has been implemented in a 0.18μm CMOS process.When the LNA and the down-converter are directly connected,the measured noise figure is 5.2dB,the measured available power gain 12.5dB,the input 1dB compression point -18dBm,and the third-order input intercept point -7dBm.The receiver front-end draws 13.6mA currents from the 1.8V power supply.When the up-converter and pre-amplifier are directly connected,the measured noise figure is 12.4dB,the power gain is 23.8dB,the output 1dB compression point is 15dBm,and the third-order output intercept point is 16dBm.The transmitter consumes 276mA current from the 1.8V power supply.
