hi all
i'm looking for RF power amplifier, or the easiest way to amplify a signal 50-60 Mhz with gain 10 or 20dB. i tried looking for ICs or circuits, & i found some ICs like AD8353 & AD8354, but they don't fit on a tested board,
+ idk if they would give me the desired power level.
(the power amplifier is for a "metal detector using GPR" transmitter)
i'm still googling for more alternatives
any advise would be appreciated

btw, i earned my Userneame, fair & square

 

Hello,

How many signal do you want at the output of this amplifier?
You could take a look for the MAR or ERA series.
