Abstract
It briefly introduced the features,application and typical application,absolute maximum ratings,package and pin functions, DC electrical characteristics ,AC electrical characteristics ,typical AC performance characteristics, typical DC performance characteristics,test circuits and applications information of The LT5527 active mixer. The LT 5527 active mixer is optimized for high linearity,wide dynamic range downconverter applications. The ICincludes a high speed differential LO buffer amplifier driving a double-balanced mixer. Broadband, integrated transformers on the RF and LO inputs provide singleended 50? interfaces. The differential IF output allows convenient interfacing to differential IF filters and amplifiers,or is easily matched to drive 50? single-ended, with or without an external transformer. The LT5527’s high level of integration minimizes the total solution cost, board space and system-level variation.
