发明名称 Integrated circuit television receiver arrangement
摘要 According to one or more aspects of the present invention, a receiver arrangement is disclosed that is configured to receive digital television signals. The receiver arrangement has at least one first frequency conversion device with the signal input, a local oscillator input and an output. The at least one first frequency conversion device is designed to convert a signal which is applied to the input side to an intermediate frequency. A first amplifier is also provided and is designed with amplification in order to compensate for the signal level loss in a filter which is connected downstream from the first amplifier. The first amplifier is coupled to the output of the frequency conversion device. An intermediate-frequency amplifier with a variable gain factor is also provided, and is coupled to the first amplifier. At least the at least one first frequency conversion device the first amplifier are formed in a common semiconductor body.
