Pictures with the shield removed. I can't measure the power with this thing, but I expect it to be over the EU limited less than 100mW (20dBm) of the RC transmitters. According to other people is capable of 200mW? It will not work (led will not go blue) unless the input antenna is connected to an input source. The marking on the chip is scrapped, but I believe is a SE2576L chip by Skyworks Solutions. Details about this chip here: http://www.skyworksinc.com/Product/953/SE2576L XQ-02A is a bi-directional signal amplifier module designed for the 2.4GHz band. Features automatic direction (send or receive) identification and switching. According to schematics, maximum output peak power is 2W, but I assume this is not the case of the current PCB. Maybe the voltages must be adjusted, judging by other reports this is doing about 200mW maybe? In my quick testing, connected directly to the TX, the chip is not getting hot, barely warm, so not sure if I need to do something else or the low temperature is maybe of the reduced power output.
