Abstract :
In this paper, we present one more efficient LINC-outphasing power amplifier using a new model of Chireix combining system. In this model we use high response time MEMS (micro electro mechanical system) switches to connect and disconnect two different stubs at the input of the Chireix combiner. This exchange of two stubs is occurred at a fixed level of the phase between the two input signals in order to improve the overall efficiency of the Chireix power amplifier. ADS simulation is used to study and validate all cases of the improved efficiency
