Abstract

In a transmitting arrangement a power amplifier is coupled to a radio-frequency antenna arrangement via a controllable matching apparatus. This allows direct impedance transformation of the output of the power amplifier to the input of the radio-frequency antenna arrangement. There is no need for transformation to the 50 ohm standard. The power amplifier, matching apparatus and a control circuit for controlling the impedance of the matching apparatus form a functional unit, which is advantageously in the form of a monolithically integrated structure in a semiconductor body. A receiving arrangement is produced in the same way, comprising an antenna, a filter device and a matching apparatus connected between them.
