    Hello ,

    If you look on page 2 of the LT5560 datasheet, you'll see that the Absolute Maximum RF input power is +10dBm. There is also Note 1 on page 4 that states that exposure to these limits may effect device reliability and lifetime.

    There is no minimum input power level that will damage the LT5560. If you keep dropping the power, eventually the signal will fall below the noise floor. This point will be determined by the overall sensitivity and noise performance of your system.
