Description: The combination of EDGE’s new modulation format and different filtering
requirements means that systems designers need different methods
for measuring the quality of EDGE signals. This application note
explores measurement techniques appropriate for analyzing this new
signal format, as well as looking at ways to adapt existing GSM measurement
techniques. In fact, most GSM measurements can be applied to
the EDGE waveform with minor changes

Description: This document is part of a set of documents that describes the QUALCOMM RTR6285
RFIC and how best to use it. The RTR6285 device supports quadband UMTS (bands 1
through 6 and bands 8 through 9), quadband GSM/EDGE, GPS, and UMTS diversity
handset operation with direct conversions between RF and baseband using zero-IF (ZIF)
radio architectures.
