Based on GaN HEMT technology, this transmission line switching PA is aimed to be used as modulating stage of a 900 MHz polar transmitter. Measured results under a two-tone excitation support the need for predistorting functions.}, organization = {This work was supported by the European Commission and the Spanish Ministry of Science and Education through TARGET NoE and project TEC2005-07985-C03-01.
