SINGLE- AND DUAL-BRANCH DOWNCONVERTER ICs FOR WIRELESS BASE STATION APPLICATIONS

摘要

Anew family of single- and dual-branch converter integrated circuits has been introduced for use in mobile infrastructure base stations. The new CV series converters are all priced below $10 in volume and are available in a 6 X 6 mm QFN package, as shown above. Their small size makes them ideal for base station upgrades required to expand capacity. In addition, the performance of these converters is well suited for the newer 2.5/3 G protocols. The functionality of these converters includes high linearity RF amplification, frequency conversion, IF amplification and LO driver amplification.
