RF path:
A.
There is a SPDT RFSW to do the diversity between 2 RF ports during normal mode.
B.
For Port0, there are 2 options, U.FL0 or printed antenna by a jumper capacitor.
C.
If using on board printed antenna: Please do not cover or put anything close to the printed
antenna otherwise the radiation efficiency will be degraded. Also keep clean underneath the
printed antenna area.
D.
For Port1, there are 2 options as well, U.FL1 or RF PAD by another jumper capacitor.
E.
RF PAD: Ideally, this can bridge the RF signal to the device outside the board. Application board
designer must be caution on the impedance control of the RF pad and 50 Ohm trace at platform
board.
F.
DNSA-144 MP version might remove the unused U.FL connector.
