[Group Buy-2][D]CC2500 RF Module - GB2

Recommended Posts

It's really an incredibly low price for such a good radio chip. Well, the CC2500 is good at least, and let's hope the module is good also. I can't understand how they managed to make it so cheap.

It seems that shipment to Europe is not too expensive, so sign me up for 10. Should be enough for playing with wireless communication for a while :-)

I wonder... what would need modified on these to attach an external antennae?

 

The resistor network that adapts the impedance to the antenna would (probably) need to be changed. It's relatively tough to get it right, and it's likely that you'd get worse performance than is there already. But you could test it out and see I guess. If you found an external antenna that has the same impedance as the PCB antenna, it might be simple, but I wouldn't know what the PCB antenna impedance is, and I think many external antennas are 50 ohm impedance.
