Abstract
A system for adjusting bias power provided to a radio-frequency amplifier to increase plurality of figures of merit based on sensed characteristics of the amplifier and/or characteristics of the input or output power.
Claims20
An amplifying system comprising:
- a radio-frequency (RF) amplifier, the RF amplifier configured to receive an incoming RF signal having an input power through an input port and an outgoing RF signal through an output port, the outgoing RF signal having an output power;
- and
- a power management system configured to adjust the RF amplifier by controlling an amount of bias power provided to the RF amplifier,
- wherein the power management system is configured to sense at least one of the input power of the incoming RF signal, the output power of the outgoing RF signal, or a characteristic of the RF amplifier and adjust the amount of bias power provided to the RF amplifier based on the sensed input power of the incoming RF signal, the output power of the outgoing RF signal, or a characteristic of the RF amplifier to improve a figure of merit of the RF amplifier.

An amplifying module comprising:
- a radio-frequency (RF) amplifier configured to receive an incoming RF signal having an input power through an input port and output an outgoing RF signal through an output port, the outgoing RF signal having an output power, the RF amplifier configured to be operated in a saturation mode in which the output power is approximately equal to saturation power of the RF amplifier and a non-saturation mode in which the output power is less than the saturation power of the RF amplifier;
- and
- a power management system configured to transition the RF amplifier between the saturation mode and the non-saturation mode by adjusting an amount of bias power provided to the RF amplifier.
An amplifying module comprising:
- a radio-frequency (RF) amplifier configured to receive an incoming RF signal having an input power through an input port and output an outgoing RF signal through an output port, the outgoing RF signal having an output power;
- and
- a power management system configured to change a class of operation of the RF amplifier by controlling an amount of bias power provided to the RF amplifier.
