Receiver arrangement with AC coupling

A receiver arrangement with AC coupling, comprising:

• an input configured to receive a radio-frequency signal;
• a frequency converter coupled to the input and configured to produce a baseband signal at its output;
• a variable gain baseband amplifier coupled to the output of the frequency converter, and having a control input for varying a gain thereof;
• a filter arrangement for AC coupling, comprising an input coupled to an output of the variable gain baseband amplifier, the filter arrangement comprising:
• a high-pass filter configured to filter the baseband signal, having a cut-off frequency that is switched between at least two values, with a lower of the at least two cut-off frequencies used during normal operation and with a higher of the at least two cut-off frequencies used in a changeover mode, and having a control input for varying the cut-off frequency;
• and
• a selectively activatable low-pass filter having a control input;
• a control circuit coupled to the control inputs of the variable gain baseband amplifier and the filter arrangement, and configured to activate the higher cut-off frequency of the high-pass filter and activate the low-pass filter during the changeover mode based on a readjustment of the gain of the baseband amplifier.
