good morning ,
i've tried to mesure an RF signal at 5.8GHz with an input power from 0dbm to 10dbm but the problem is that the output voltage for the range of power 5dbm to 10dbm was the same (Vout=1.4V).
the input power as a maximum rating for the LT5581 is 15dBm (mentioned in the datasheet) .
how can i solve this problem please .
