Hello people!
Trying to transmit (and succeeding) in the ISM BWs at 315 and 433 MHz using a 3.3V radio transmitter IC + PCB trace antenna.
Current setup: separate boards for each one of the two ISM BWs; the antenna is adapted by a different set of capacitors to the 315 or 434 MHz BWs respectively, and fed 3.3V through a different value inductor.
Current goal: have just one PCB manufactured instead of two and a way to switch between the two adaptations of the same PCB trace antenna, or any other practical way to have only one PCB for both BWs and some sort of antennas (external ?) that I can quickly solder / thread in, reflash the device and use it in the other BW. Doable ?
Thanks!
