  • Publication number: 20220103140
    Abstract: An envelope stacking power amplifier system reduces current for a given output power level without sacrificing the ability to support large voltage swings at saturation and therefore increases efficiency at the maximum linear operating power and all power levels below that. The system includes a stack/unstack controller including circuitry configured to switch the RF power amplifier system between a stacked mode in which first and second RF amplifiers are coupled in a stacked configuration and an unstacked mode in which the first and second RF amplifiers are coupled in an unstacked configuration in response to one or more mode-control signals, the stacked configuration providing reduced current compared to the unstacked configuration.

  • Patent number: 9190962
    Abstract: A radio frequency (RF) power amplifier (PA) is reconfigured to operate in a low power mode from a high power mode. The RF PA has a first RF amplifier is connected to the first and second inputs of a first transformation network. The RF PA has a second a second RF amplifier connected to a second transformation network. During high power mode, both RF amplifiers drive a load coupled to the transformation networks. In low power mode the first RF amplifier is disabled and the first and second inputs of the first transformation are coupled together so as to change the load impedance seen by the second RF amplifier. The second RF amplifier continues to supply power to the load during operation in the low power mode.

  • Patent number: 9136809
    Abstract: An RF power amplifier operates over the range of supply voltages provided by a DC/DC converter whether the range of voltages is intentional or unintentional. A system for digitally adjusting the bias levels relative to the supply voltage includes at least one RF power amplifier stage, a digital control block, and a bias circuit. The RF power amplifier stage has at least one RF input signal, at least one RF output signal, and at least one bias input that controls its bias conditions. The RF Power Amplifier Stage includes one or more active gain elements used to amplify the RF input signals. The RF power amplifier operates in a number of bias states controlled by the digital control block. The digital control block uses information related to the supply voltage and may use other information stored in memory to select the desired bias.

  • Patent number: 8922282
    Abstract: A radio frequency (RF) power amplifier includes a low impedance pre-driver driving the input of a common-source output amplifier stage. The preamplifier includes a first transistor that has a first terminal coupled to a preamplifier RF input node, a second terminal coupled to a preamplifier RF output node, and a third terminal coupled to a supply voltage node. A first inductor is coupled between the RF output node and a bias voltage node. A voltage difference between respective first and second voltages on the RF input node and the RF output node that are substantially in phase, determines current through the first transistor.
