Abstract :
This paper presents the application of a reconfigurable MEMS-based tuning network for the improvement of the linearity and efficiency in RF power amplifiers (PAs) under load variations. Simulations show the performance improvement of the whole system in terms of linearity and efficiency with different loads.
