Envelope Tracking Simulation, Design and Test Solutions

The push for higher data rates in mobile devices is driving wider bandwidth, higher peak-to-average power transmission schemes like LTE. Envelope tracking is a technique which can improve power amplifier efficiency and linearity, resulting in longer battery life, less heat dissipation and wider frequency coverage in LTE handsets. Explore Agilent’s industry-leading envelope tracking tools for power amplifier and power supply design and characterization.
