This paper presents an end-to-end high frequency class S power amplifier. A description of the full testbench and some important points on generation of RF outputs from FPGA devices and current mode class D design are given. Experimental measurements are provided for the prototype PA consisting of a signal generator, analog to digital converter, driver circuit, current mode class D switching stage and bandpass filter. Theory and experimentally measured results for this prototype are presented for a multi tone signal centred at 930 MHz and with a total output power of 24.7dBm.
