A low power, high performance BiCMOS MIMO/diversity direct conversion transceiver IC for WiBro/WiMAX (802.16e)
Revisions to earlier work:
These filter architectures developed by Southampton/Philips are now the default for baseband channel selection in zero and low IF integrated radio as well as other communication ICs. The integrated filters used in the submitted design were optimised for a wide range of channel bandwidths needed for WiMAX with high linearity and low power.
Significance of output:
This paper describes a fully integrated radio transceiver IC with two zero-IF MIMO/diversity receiver channels for the WiMax data transmission standard. The academic returnee architected and designed the self-tuning self-calibrating channel filters (based on past Southampton University research work) that are used to compensate for component tolerances as well as adjust for the instantaneous data rate. A direct up-conversion transmitter is used with similar filter structures. The IC meets the WiMax specifications without trimming due to extensive use of digital correction and calibration of analogue and RF circuits. The IC is a commercial product (NXP UXA23465/66).
