Chip eases direct conversion receiver designs

摘要

Linear Technology won a 2007 Product of the Year award for its LT5575 direct-conversion I/Q demodulator. We recently spoke to Design Manager Min Zou about the product's development. "The concept for the LT5575 was to design a direct conversion receiver with a flexible architecture, capable of covering multiple RF standards while simplifying system design and reducing overall costs. Although direct conversion receiver designs had been widely used in cordless phones and cellular handsets, they had not proliferated in base stations, even with their lower costs, due to performance limitations," Min Zou told us.
