  • Radio frequency power monitor
    Patent number: 8027648
    Abstract: An exemplary apparatus for monitoring power of RF energy includes a transmit/receive switch configured to switch an antenna between a transmitter state and a receiver state. The switch includes a diode. The exemplary apparatus can include an output device configured to monitor voltage across the diode of the switch to detect power of RF energy of the antenna. An exemplary method of monitoring power during transmission or reception of a signal can include placing a transmit/receive switch configured to switch an antenna between a transmitter and a receiver into one of a receiver state or a transmitter state. The exemplary method can include detecting voltage across a diode configured as a switching element in the transmit/receive switch to monitor power, and providing an output indicative of the monitored power.
