You mean that you want to cover the whole frequency range you specify?
The only easy way I can think is to try a wideband VCO followed by a wideband amplifier.
Try the MAX2606 VCO 45-650MHz in combination with the MAR2 amplifier also wide range. You can find them in small quantities from gk-electronics.gr
It will give you enough power to transmit up to 100 meters or so I think.
