Performance analysis and hardware design of digital transmitter system base on ZIF

Abstract

The RF systems of Digital Broadcast Transmitter generally take two forms, ZIF and DIF structure. Based on ZIF, this paper focuses on the relationship among phase imbalance, amplitude mismatch and RF performance, such as sideband suppression and modulation error. These theoretical analysis and stimulated performance provide more guidance on hardware design and debug for digital television transmitter system, based on ZIF structure.
