Patent ID: 8731492

Claim:
A system for monitoring and controlling the power of a Radio Frequency (RF) signal in a short range RF transmitter, said RF transmitter comprising an RF signal generation unit for generating the RF signal, a power amplifier for amplifying the RF signal, and an antenna for radiating the amplified RF signal, said system comprising: an RF power monitoring unit for connecting to an output stage of at least one component of the transmitter, for monitoring a power of the RF signal and generating at least one alarm signal indicating a faulty condition when said power meets a predetermined alarm criterion revealing a failure of at least one of said RF signal-generation unit, said power amplifier and impedance-matching network; and a control unit connected with an input to said RF power monitoring unit and for connecting to an output to a control input of at least one component of said transmitter for modifying at least one operating parameter of at least one of the RF signal generation unit and the power amplifier in response to said alarm signal, wherein said control unit is arranged to restart a telegram transmission of said RF signal after modifying said operating parameter.
