Abstract: A peak detector for a power amplifier is provided that includes a threshold voltage detector configured to pulse a detection current in response to an amplified output signal from the amplifier exceeding a peak threshold. A plurality of such peak detectors may be integrated with a corresponding plurality of power amplifiers in a transmitter. Should any peak detector assert an alarm signal or more than a threshold number of alarm signals during a given period, a controller reduces a gain for the plurality of power amplifiers.

Abstract: In certain aspects, a method is provided for measuring power using a resistive element coupled between a power amplifier and an antenna. The method includes squaring a voltage from a first terminal of the resistive element to obtain a first signal, squaring a voltage from a second terminal of the resistive element to obtain a second signal, and generating a measurement signal based on a difference between the first signal and the second signal. In some implementations, the resistive element is implemented with a power switch.

Abstract: A method and apparatus for linearizing a baseband filter are provided. The apparatus is configured to, via a first conducting module, receive a first current signal. The apparatus is further configured to, via a converting module, receive a second current signal, generate a voltage signal based on the second current signal, and apply the voltage signal to the first conducting module. An amount of the second current signal received by the converting module is based on an amount of the first current signal flowing through the first conducting module. The apparatus is also configured to, via a second conducting module, control an output current signal based on the voltage signal. The output current signal is controlled to be a linear replica of the first current signal for in-band frequencies.
