Need a Low pass filter, pleas help!

Hi all, I need a 30-50mhz low pass filter to filter 2nd and 3rd harmonics. Is there anyone know a company which can provide this kind filter? Specs: S11<-25DBC from 30-45mhz, Handle power> 150W cw. Thanks!

I suppose, you need a 30-50 MHz (not mHz) filter, correct?

Look for amateur radio filters like this:

VSWR 1.2 = 21dB return loss
