  • System for monitoring and controlling the power of a radio frequency (RF) signal in a short-range RF transmitter
    Patent number: 9491723
    Abstract: A system for monitoring and controlling the power of a Radio Frequency (RF) signal in a short-range RF transmitter. An RF signal-generation unit generates the RF signal. A power amplifier amplifies the RF signal. An impedance-matching network matches the output impedance of the power amplifier to input impedance of an antenna. One or more RF power monitors monitor the voltage amplitude of the RF signal at the output of at least one of the RF signal-generation unit, the power amplifier and the impedance-matching network. The one or more RF power monitors further generate at least one alarm signal, based on the voltage amplitude of the RF signal. A control unit modifies at least one operating parameter of at least one of the RF signal-generation unit and the power amplifier, based on the at least one alarm signal generated by the one or more RF power monitors.
