Wireless transmitters employing switching power amplifiers are popular both in RF and mm-wave designs. The efficiency of switching power amplifiers is dictated mainly by the maximum achievable switch size which in turn is governed by the switch transition frequency (trade-off between switch on-resistance and capacitance). This work presents a new architecture, the Distributed Switching Power Amplifier (DSPA), that helps break this trade-off by distributing the switch in the non-linear amplifier design, especially at high frequencies. A comprehensive analytical framework has been developed and the theory has been compared with simulation results.
