摘要： 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.

摘要： Real power delivered to a load in an RF transmit path is measured. Measuring the real power includes supplying a first voltage from a first side of a passive network disposed between the power amplifier and the load, supplying a second voltage from a second side of the passive network; and using the first and second voltages and a phase delayed voltage to determine the real power delivered to the load. A voltage difference between the first and second voltages is determined and multiplied by the phase shifted voltage. A low pass filter is then applied to the output of the multiplier to provide an indication of the real power consumed by the load. The indication of real power consumed may then be used to control the power amplifier.

摘要： 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.
