RF switch controlled by SW

Controls which RF interface goes to the RP-SMA external antenna

These values configure the required pin to drive the RF antenna switch, to either enable the sub-1Ghz RF interface (power-up the CC1200) or the 2.4GHz RF interface of the CC2538, both alternatively routed to a RP-SMA connector to allow using an external antenna for both cases.

Note it is also possible to enable both RF interfaces at the same time, by switching On the sub-1GHz RF interface, and placing an 0Ohm resistor (R19), to select between using a ceramic chip antenna (not mounted), or to connect and external antenna over a pigtail to the U.Fl connector (not mounted).

RF switch state:

  • LOW: 2.4GHz RF interface on RP-SMA connector, CC1200 powered-off.
  • HIGH: Sub-1GHz RF interface on RP-SMA connector.
