This paper describes a dual signal path (MIMO) low power, high performance direct conversion WiBro/WiMAX 802.16e radio transceiver optimized for mobile applications and coexistence with on-board cellular and WLAN/Bluetooth systems. It is fabricated in a SiGe BiCMOS process and achieves a receiver NF of less than 2.5 dB over an operation frequency of 2.3-2.7 GHz. The transmit gain can be digitally tuned over a 75 dB range. The transceiver consumes 65/103 mA at a 2.8 V supply in OFDMA Rx/Tx modes respectively.
