  • Method for detecting an oscillation in an on-frequency repeater
    Patent number: 7593689
    Abstract: A method of detecting oscillation in an on-frequency repeater having an RF signal path coupled between an input antenna and an output antenna. In accordance with the present invention, a first RF signal power level within the RF signal path is detected during an un-muted period in which transmission of an output RF signal through the output antenna is enabled. A second RF signal power level within the RF signal path is detected during a mute period in which transmission of an RF signal through the output antenna is disabled. The first and second detected RF signal power levels are then compared, which provides an indication of signal leakage, and thus oscillation.
