Abstract

This paper discusses the system level analysis of Envelope Tracking (ET) power amplifier (PA) applied to FDD transceivers by X-parameter model. In particular, efficiency and linearity of the transmitter are analyzed. Additionally is analyzed the receiver desensitization issue, due to the interaction with the transmitter. The system-level analysis led to the possible trade-offs between the several system parameters, the implementation constraints and the system performance, as well as the most critical aspects for the effective development of ET-PA capable to deal with wide bandwidth signal.
