RF driver / RF amplifier that has P1dB output at least 33dBm

RF driver

Hi all,

I am looking for an RF driver / RF amplifier that has P1dB output at least 33dBm. THe frequency range is primarily 50-150MHz, but wider range is also ok. Efficiency is the issue here, as i already have one that has 25% efficiency(34-35dBm output with 12V@1000mA power supply). Anybody has any advice on this, schematic or even a device to recommend?Any help is appreciated. Thanks!

Re: RF driver

Just look on minicircuits site or google, and find an Amp w/ P1dB ~= 40 and the
rest should take care of itself. But 12V might be too low! Come to think of it
this amp has to almost be 100% efficient from DC to RF power conversion!

12Vdc Max Amp Rail ! Assuming a 50Ω system ! You highest possible Pwr =

P= 12^2/50 = 2.88W = ~34.5dBm (This can only happen in a text book)

You'll need to put a buck converter to bring that DC up, or something clever.
