Abstract: A load modulated balanced amplifier (LMBA) circuit can include an input pad of the LMBA circuit configured to receive an input signal on a semiconductor die. A transformer-based hybrid splitter can be coupled to the input pad and configured to provide a first split input signal and a second split input signal from the input signal. A control power amplifier circuit coupled the first split input signal and a power amplifier circuit coupled to the second split input signal.
