CMOS技术是把L波段卫星调谐器、解调器和其它功能整合至低成本、高效能单芯片的关键。本文将探讨新型低中频和传统零中频DBS调谐器架构在单芯片DBS射频前端设计中的优缺点。
CMOS technology is the key to integrating L-band satellite tuners, demodulators and other functions into low-cost, high-performance single-chip. This article explores the pros and cons of the new low-IF and traditional zero-IF DBS tuner architectures in a single-chip DBS RF front-end design.
