Abstract

A transmitter integrating a passive FET Quad up-conversion mixer, a power amplifier with output P_1dB of 23 dBm, a transmit/receive (T/R) switch with an insertion loss of 1.1 dB and output P_1dB of 21 dBm has been implemented in a 0.25-μm foundry CMOS process. The transmitter at the output power level of 16.5 dBm is compliant to the 802.11b specifications at 11 Mbps. This circuit is the first 802.11b transmitter to have the entire function integrated including a PA and a T/R switch.
