Circuit with a traveling wave amplifier for high frequency signals has many amplification steps and a differential amplification step to adjust the work point of each amplifier

摘要

A circuit having a traveling wave amplifier (1) for high-frequency signals comprises many amplification steps (6a-c) with at least one active element (7a-c). A circuit (7,13,14a-c) comprising a differential amplification step (7,13) adjusts the work point of each active element.
