CC1101 RF modem + 250mW amplifier published
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.
After adding RF amplifier, original power of 10mW is boosted to almost 250mW or 1/4W. MAX2233 RF amp can deliver up to 250mW when powered by 3.6V, and since I used 3.3V LDO on my board, the output RF power is little less than that.
