  • Amplifier suitable for cable-network applications
    Patent number: 6023197
    Abstract: An amplifier having an inductive coupling (LL) via which a load (Z1) may be coupled between the two main current terminals (E,C) of a transistor (QA). A capacitive coupling (CC) is also provided between the two main current terminals (E,C). The inductive coupling (LL) and the capacitive coupling (CC) provide, between the two main current terminals (E,C), respective impedances (ZLL, ZCC). To achieve a satisfactory performance in terms of signal distortion and gain, impedances (ZLL, ZCC) are substantially equal in magnitude in at least a portion of a frequency range throughout which the amplifier provides gain. The amplifier is particularly suitable for cable-network applications.
