Abstract
A fully integrated low power transmitter for an IEEE 802.11b transceiver system is implemented in SMIC 0.18μm technology.The direct-conversion transmitter includes two Chebyshev I low pass filters,two PGAs,a SSB mixer,and a PA driver.The transmitter provides a gain control of 32dB in 3dB steps.The maximum output power is -3.4dBm and the EVM is 6.8%.The power consumption of the transmitter is only 57.6mW with a 1.8V power supply.The chip area of the transmitter is 1.6mm×1.6mm.-
