Abstract
This paper presents a study of thermal-memory effect reduction for multi-level pulse-modulated polar transmitters (PMPTs). PMPTs using single-level pulse modulation have shown to have minimal memory effects even when operated at high power levels. In this paper, thermal simulation with different levels of pulses was performed to study the effects of multi-level pulse modulation. Simulation results show that the multi-level pulse signal has the potential to reduce heat from base station power amplifier.
