The invention relates to a high-frequency receiver comprising a frequency converter 4, 5, to which an HF signal can be supplied and which provides a baseband signal at one output. An analog filter 8, 10, 11 is provided between the frequency converter and an analog-digital converter 12 and a digital filter is connected to the A-D converter 12 on the output side. The analog and digital filters together provide a channel filtering of the receiver, which is preferably configured as a homodyne receiver. The analog filter preferably comprises pole locations that are merely passive. The inventive circuit permits an implementation with a minimal chip surface-area requirement, high linearity, excellent noise characteristics, in addition to the use of said receiver in third-generation mobile radio telephone systems. |
