Reconfigurable High Frequency Class S Power Amplifier Demonstrator.
In: Integrated Nonlinear Microwave and Millimetre-Wave Circuits (INMMMIC 2012), 18th - 19th April, 2011, Vienna, Austria.
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.
