Abstract

A low-pass-type matching network (7) is disposed between a mixer (5) of the radio receiver which is provided to transpose the radio-frequency receive signals to an intermediate frequency and an intermediate-frequency amplifier (8). This network comprises a series circuit made up of a first capacitor (71) and a first ohmic resistor (72) which connects the output of the mixer (5) to earth, and a series circuit made up of an inductor (73) and a second ohmic resistor (75) which connects the output of the mixer (5) to the input of the intermediate-frequency amplifier (8). The connection point between the inductor and the second ohmic resistor is connected via a further capacitor (74) to earth. <IMAGE>
