摘要： An impedance matching circuit (11) is provided comprising a plurality of branches between an input node (19) and an output node (13). Each branch comprises an inductor (14A-14C) coupled in series to a series switch (16A-16C) and coupled in parallel to a parallel switch (15A-15C). Each first end of a respective inductor may be a first radio frequency output terminal.

摘要： A radio frequency switch includes a first transistor and a second transistor coupled together to establish a switchable radio frequency path, and a first compensation network coupled between the body terminal of the first transistor and the drain terminal of the second transistor, wherein the first compensation network establishes a path for current flowing between the body terminal of the first transistor and the drain terminal of the second transistor in a first direction and blocks current flowing in a second direction opposite to the first direction.

摘要： A system for controlling amplifier power is provided. The system includes a voltage envelope detector that receives a voltage signal and generates a voltage envelope signal. A current envelope detector receives a current signal and generates a current envelope signal. A power amplifier level controller receives the greater of the voltage envelope signal and the current envelope signal, such as by connecting the output of the voltage envelope detector and the current envelope detector at a common point and conducting the high frequency current components to ground via a capacitor. A power amplifier level control signal is then generated based on the voltage drop across the capacitor.
