  "textContent": "A communication device, method and computer program product provide efficient average power tracking (APT) powering of transmit power amplifiers with fewer switching mode power supplies (SMPSs) to reduce size and cost of the communication device. A controller of the communication device detects an output voltage level of a battery supply of a communication device power amplifiers (PAs) assignable to respective transmit uplinks. The communication device includes a smaller second number of switching mode power supplies (SMPSs). The communication device includes linear regulator(s) that are powered by one of (i) output voltage of the battery supply and (ii) one of the one or more SMPSs. Controller selects a combination of SMPSs and linear regulators to power active PAs. The controller determines APT supply voltage value for each PAs and assigns the SMPS(s) and the linear regulator(s) to the PAs to achieve a highest overall or combined system power efficiency.",
