what is the minimum and maximum RF input power that can be provided to LT5560 mixer for down converting application at 10.7Mhz frequency.
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.

Thanks for the information..
Although you have mentioned the minimum input power depend on the noise and sensitivity,I'm using the mixer at 10.7Mhz.. can you provide a rough estimation about the minimum power the mixer can sense because according to that i'm going to put an amplifier before the input of mixer.
