Abstract :
A 0.18-mum CMOS tri-band MIMO transceiver for fixed and mobile WiMAX applications is presented. The transceiver supports operation in the 2.3-2.7 GHz, 3.3-3.8 GHz, or 4.9-5.95 GHz bands. A novel DC-offset removal scheme is used to enable a low-cost direct-conversion architecture. The transmitter exhibits an EVM of -38 dB, -36 dB, and -33 dB @ 0 dBm output power for the 2G, 3G, and 5G bands respectively. In full MIMO operation at 3.5 GHz, the TX dissipates 402 mW and 450 mW in RX mode.
