专利名称：HIGH-FREQUENCY RECEIVER发明人：ADLER, BERND申请号：EP02737807.4申请日：20020419公开号：EP1382111A2公开日：20040121
摘要：The invention relates to a high-frequency receiver comprising a frequencyconverter (4, 5), to which an HF signal can be supplied and which provides a basebandsignal at one output. An analog filter (8, 10, 11) is provided between the frequencyconverter and an analog-digital converter (12) and a digital filter is connected to the A-Dconverter (12) on the output side. The analog and digital filters together provide achannel filtering of the receiver, which is preferably configured as a homodyne receiver.The analog filter preferably comprises pole locations that are merely passive. Theinventive circuit permits an implementation with a minimal chip surface-area requirement,high linearity, excellent noise characteristics, in addition to the use of said receiver inthird-generation mobile radio telephone systems.
