There are dozens of PLL synthersiser IC's that could be used along with a bunch of extra bits.
You need to give more detail to get sensible answers.
How many frequencys within that band do you need? FM? Some other modulation scheme? Do you want to send analog or digital signals?
For a single fixed frequency with a typical varactor diode FM modulator and superhetrodyne FM receiver it may make sense to use a couple of crystal oscillators instead of a synthersiser.
RF takes experiance to get things to work well.
Being a bodger at heart for 40Mhz I'd be considering buying a load of basic 27Mhz CB radio's, adding a little board with a couple of crystal oscillators for TX and RX LO and changing about a dozen capacitors. Guessing from the retail prices CB radios must be available wholesale for about 5$ each. Not ideal if you have portable use in mind.
