摘要： A pre/post-distortion circuit particularly for microwave radio-frequency systems is disclosed. The pre/post-distortion circuit according to the present invention, comprising an input signal (I) controlled attenuator (AT), is characterized by further comprising divider means (DI) for properly subdividing said input signal (I) and transmitting it to respective channels (A, B, C), a first (C) of said channels comprising means (PS, DC) for repeating or cloning, from a distortion point of view, the signal whose circuit one wishes to pre/post distort, the others (A, B) of said channels comprising substantially linear networks (LN), and adding means (AD) to sum the signals coming out of said channels (A, B, C). A method is also disclosed for pre/post-distorting a signal, particularly in radio-frequency systems.

摘要： A linearizing circuit (CI) for linearizing the output (OU) of an apparatus (TR), the circuit including a splitter (DI_IN) for subdividing the input signal (IN) into at least first (IN1) and second (IN2) portions and a circuit (DI_OU) for picking up a portion of the signal coming out from the apparatus (TR) to be linearized. The circuit is characterized in that it further includes a first adder (AD1) for adding the picked-up portion of the output signal with the second portion (IN2) of the input signal (IN) and outputting an individual signal which is in turn added to the first portion of input signal (1N1) through a second adder (AD2). A method is also disclosed for linearizing the output of an apparatus, e.g., a power amplifier.
