RF AM Transmitter Circuit Design

I require a circuit to be designed for an RF transmitter as follows: - AM on-off-keying transmitter - RF frequency 476.975MHz, bandwidth 12.5KHz - Transmit power 2W - Data rate up to 10kbps - Transmitter supply voltage 6V - Quiescent current <10uA - Data signal to be supplied is 0-5V, manchester encoding - Schematic only required - Design to include recommendations on Antenna design for quarter and half wave lengths, PCB and wire styles. Any other required information can be provided upon request.
