Three different methodologies are compared, which are suitable for saving battery current of a power amplifier operated in back-off. Dynamic Voltage Biasing (DVB), Dynamic Current Biasing (DCB), and Load Modulation (LM) have been paired in three different ways and experimentally tested for the first time on the same power transistor to achieve meaningful conclusions. Measurement results from on-wafer load-pull investigation of a SiGe power cell identify the combination of DVB and DCB as the most profitable strategy. This mode manifests a power added efficiency higher than 75\% for an excellent 14dB back-off dynamic.
