Question
Can you use the ADL5511 with different input carrier frequency signals?
Answer
Using the ADL5511 with different input frequencies is not a problem. You
basically need to configure the device to accept the lowest expected frequency
and then it will work fine with all other (higher) frequencies. Please refer
to the section of the datasheet entitled "Operation below 1 GHz/Envelope
Filtering". This will explain the changes that need to be made to FLT1 and
possibly FTL3 and FLT4.
