    摘要: A connector unit comprises a case, a substrate and a connector. The case is formed with an opening. The substrate is installed within the case and is formed with a signal conductive pattern and a ground conductive pattern. The ground conductive pattern is electrically connected to the case. The connector comprises a contact, an outer conductor and a high impedance member. The outer conductor is electrically connected to the ground conductive pattern. The outer conductor is insulated from the contact but covers, at least in part, the contact. The contact is electrically connected to the signal conductive pattern. The high impedance member has high impedance in a high frequency range. The high impedance member is positioned between the outer conductor and the case within the opening of the case. For example, the high impedance member is an electric wave absorber.

    摘要: In a feed forward amplifier, an RF amplifier is supplied with an input RF signal at an input terminal for amplifying the same; a distortion extraction loop supplied with the input RF signal and further with the output RF signal from the RF amplifier is for extracting non-linear distortion components formed in the output RF signal as a result of amplification in the RF amplifier; a variable phase shifter is provided in the distortion extraction loop for varying a phase of the input RF signal; a variable attenuator is provided in the distortion extraction loop for attenuating an amplitude of the input RF signal that has been supplied to the distortion extraction loop; and a distortion extraction circuit is provided in the distortion extraction loop for producing a distortion output signal that includes non-linear components; further, a control circuit is supplied with the input signal and with the distortion output signal for extracting a main signal component contained in the distortion output signal. The control circuit controls the variable phase shifter and the variable attenuator such that a ratio of the main signal component level with respect to the input RF signal level is decreased.
