There are many components that amplify small signals and power signals in this band, no doubt.RFMD, Skyworks, MACOM, etc etc.. many suppliers have a large portfolio for LNAs and PAs.You will also need RF switch to commutate the antenna RX and TX mode. For switches Peregrine Semiconductors is the best one but the other manufacturers have low cost switches too.
All you need to implement these component on a PCB with of course matching circuits, filters -if applicable- and surely power supply circuit(s). In order to implement such a TX/RX module, you can find very useful information on the internet.If you wait, I can propose a simple block diagram but you'd better to design your system by yourself for learning something.
