Hi Oigres,

You are not entirely clear with your request. Need to give as much detail as you can like what application and intended topology before we can help you.

you may refer to RFMD's rf2510/rf2512 architechture
they are ask/fsk tx
for a fsk tx, you can modulate the vco directly
for a ask tx, you can turn on/off the driving amplifier
after the circuit arch is determinated, it is what you are trainned to
implement it!!
