发明名称 Pre/post-distortion circuit and method, particularly for microwave radio-frequency systems
摘要 <p>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. &lt;IMAGE&gt;</p>
