| Abstract: | A fully integrated system-on-a-chip (SOC) intended for use in 802.11b applications is built in 0.18-/spl mu/m CMOS. All of the radio building blocks including the power amplifier (PA), the phase-locked loop (PLL) filter, and the antenna switch, as well as the complete baseband physical layer and the medium access control (MAC) sections, have been integrated into a single chip. The radio tuned to 2.4 GHz dissipates 165 mW in the receive mode and 360 mW in the transmit mode from a 1.8-V supply. The receiver achieves a typical noise figure of 6 dB and -88-dBm sensitivity at 11 Mb/s rate. The transmitter delivers a nominal output power of 13 dBm at the antenna. The transmitter 1-dB compression point is 18 dBm and has over 20 dB of gain range. |
