efficient, low cost, high gain rf cellular power amplifer

Post by qwerty15 » Thu Oct 11, 2007 8:47 am

hi,

I am looking to design an efficient, low cost, high gain dual band rf cellular power amplifer. does anyone have any schematics they have used in the past? any good antenna designs if any, etc?

maybe i should use a class A amplifier with two diplexers and a lot of filtering? what are your thoughts?

thanks in advance!
