Introduction

If the Wireless LAN market is still growing, Wireless LAN solutions are already in a cost reduction phase. Conceiving WLAN solutions nowadays requires a high-level approach where the final chipset may be better partitioned or reduced to one chip, where the number of external components has to be reduced, where the die size and the technology choice is crucial. The radio chip, for instance, has to be compliant with the numerous standards of the WLAN market, used in at least four radio-frequency bands.

We present here a WLAN radio where the system architecture solves the sum of problems created by multi-band and multi-standard applications. Our solution is compliant with the 802.11a/b/g standards. Then we present some of the techniques used in design to build this solution as a highly integrated, reduced die size, chip in a 0.18um RFCMOS low cost technology. This chip design is available as an Intellectual Property product.
