 The insertion of EMI filter on VBATT pins is suggested in those designs where
antenna is placed close to battery or supply lines. A ferrite bead like Murata
BLM18EG101TN1 or Taiyo Yuden P/N FBMH1608HM101 can be used for this
purpose.
 The below figure shows the recommended circuit:
VAUX Power Output
A regulated power supply output is provided in order to supply small devices from the
module. The signal is present on Pad R11 and it is in common with the PWRMON
(module powered ON indication) function.
This output is always active when the module is powered ON.
The operating range characteristics of the supply are:
Item Min Typical Max
Output voltage 1.78V 1.80V 1.82V
Output current - - 60mA
Output bypass capacitor
(inside the module)
1uF
