Here is my home-built, cloth iron soldered, range extender for CC1101 (included onboard) RF transceiver chip from Texas Instruments. You could say that it is a CC1101+CC2591, but for 868/920MHz band. I used MAX2233 RF amplifier from Maxim-IC. It can deliver up to +24dBm (250mW) of RF amplification with +10dBm of input.

any reference you can give for cloth iron soldering of SMD? I guess most of this is strait forward, but im curious on tips for priming the pads before laying down
thanks

hi,
in the process you might need to use tweezers to adjust some components if they start moving around because the solder might attract them on one side.
what information do you need because it IS strait forward; just put some solder on the PCB, place components and put it on a cloth iron, in around 30 seconds it is all done
that is all. you really must try it to see how it works. also google for hot-plate-soldering, it is the same thing.
