Box 9106 Norwood, MA 02062-9106 781/329-4700 World Wide Web Site: http://www.analog.comDesigning a Superheterodyne Receiver Using an IF Sampling Diversity Chipsetby Brad BrannonAbstract: The paper introduces a chipset to simplify receiver design and puts forth a design example based on GSM but can be extended to many open or closed air interface. Advances in analog converter technology now allow IF sampling which can greatly simplify receiver design. Advances in digital integrated circuits also advance the state of the art in terms of digital tuning and filtering. Together these two chips can replace many of the cumbersome stages of a traditional analog receiver with predictable and reliable performance.The superheterodyne recei……
