Brian Nissim, Steven Lyuee, Paul Yu, Todd Sepke, Shervin Shekarchian, Luns Tee, Paul Muller, Jonathan Tam, Thomas Cho Marvell Semiconductor, Santa Clara, CA Growing demand in the broadband wireless communication market has resulted in emerging standards such as IEEE 802.16e (mobile WiMAX), which enable high data-rate communication over wide area coverage. Seamless switching between WiMAX and WLAN is envisioned as a means to enable users to stay connected anywhere and anytime. A low-cost low-power smallform-factor dual-mode (802.16e and 802.11b/g/n) dual-band (2.3G to 2.7G and 3.3G to 3.9G) 2×2 MIMO direct-conversion radio in 90nm CMOS has been developed to address this rapidly growing market. The transceiver supports wide dual-frequency bands and multiple signal bandwidths of 3.5, 5, 7, 10, 14, 20, and 40MHz for worldwide dual-mode operations. Many key challenges in WiMAX direct-conversion transceiver design stem from its small subcarrier
