The Load-Modulated Linearizer: A Technique for Intermodulation Cancellation in PA Systems
2022 IEEE BiCMOS and Compound Semiconductor Integrated Circuits and Technology Symposium (BCICTS), 2022 A novel application utilizing the load-modulated balanced amplifier (LMBA) principle to actively absorb individual out-of-band intermodulation components at the output of a power amplifier operating in high compression is presented. The system requires nearly the same amount of additional power as the IMD power it absorbs, making it very efficient.
