Integrated Circuit for Transmitting and Receiving an RF Signal

摘要

An integrated circuit, comprising a single-ended pin for transmitting and/or receiving an RF signal. A first matching network is configured to match an impedance of the RF signal. A second matching network is configured to match an impedance of an on-chip differential circuit. A third matching network is configured to match an impedance of an on-chip single-ended circuit, wherein the third matching network is connectable to the first matching network. A transformer is connected or connectable to the second matching network and to the first matching network. Switches control an operating mode of the integrated circuit The second matching network is connected with the first matching network via the transformer, or the third matching network is connected with the first matching network.
