A low power, high performance SiGe BiCMOS 802.1 6e dual conversion transceiver IC

Abstract

This paper describes a low power, high performance double 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 2.5dB at an operation frequency of 2.35GHz. The transmit gain can be digitally tuned over a 75dB range. The transceiver consumes 125/135mA at a 2.8V supply in OFDMA Rx/Tx modes respectively.
