    摘要: A high frequency receiver cancels a plurality of noise signals which are contained in a high frequency signal and outputted from a plurality of noise signal sources. The high frequency receiver cancels the noise signals using a plurality of pick-up noise signals extracted from a plurality of pick-up antennas disposed near the noise signal sources. At least one of the pick-up noise signals is selected in descending order of their effects on the degradation of reception quality, thereby completing noise cancelling in a short time.

    摘要: An antenna matching unit includes an antenna matching device to which a first high-frequency signal and a second high-frequency signal with a frequency higher than that of the first high-frequency signal are input; an active element to which an output signal from the antenna matching device is connected; and an output terminal to which an output from the active element is connected. The antenna matching device includes a signal line placed between the input and output; a series-connected element composed of a capacitor and inductor connected between the signal line and the ground; a capacitor connected in parallel with the inductor; and a control terminal for changing the capacitance value of the capacitor. The parallel resonance frequency between the inductor and capacitor is set to the frequency of the second high-frequency signal to reduce matching loss between the antenna and the tuner unit.
