Claim Text:
1. An RF receiver device, comprising: a chip package; a semiconductor chip included in the chip package; a test signal generator integrated in the semiconductor chip, the signal generator configured to generate an RF test signal including first information; an RF receive channel including an RF receiver circuit integrated in the semiconductor chip and having an input configured to receive an RF input signal, and further configured to down-convert the RF input signal into an intermediate frequency (IF) or base band and to digitize the down-converted signal, thus providing a digital signal; wherein the RF receive channel further comprises a coupler integrated in the chip package and having a first input port and a second input port and an output port, wherein the output port is coupled to the input of the RF receiver circuit, the first input port is configured to receive an antenna signal, and the second input port is coupled to the test signal generator and configured to receive the test signal; and a signal processor integrated in the semiconductor chip, wherein the signal processor is configured to determine, during a test cycle, whether the first information present in the digital signal matches a predetermined criterion.
