STEP 1:
AEM30940 Configuration
•
MPPT ratio:
SELMPP0
–
SELMPP1
•
Storage Element voltages protection:
CFG2
–
CFG1
–
CFG0
•
BAL option:
Select
“
ToCn
”
for dual-cells supercapcacitor and
“GND”
for any other
storage
•
PRIM option:
Connect both jumpers
“
NoPRIM
”
or remove them if a primary
battery is connected. Define the lower limit voltage on the primary battery using
R7 and R8:
•
100 k
Ω ≤
RP
≤
500 k
Ω
•
R7 =
(
𝑉𝑝𝑟𝑖𝑚_𝑚𝑖𝑛
4
* RP) / 2.2 V
•
R9 = RP
–
R7
•
ZMPP resistor footprint
•
LDOs Outputs Voltages:
ENHV (HVOUT)
–
ENLV (LVOUT)
•
MATCHING RF RECTIFIER:
one matching for LOW input power (< -10 dBm)
and another matching for HIGH input power (< +20 dBm)
STEP 2:
Connect the Storage Element (and the Primary Battery)
STEP 3:
Connect the Load(s) to HVOUT / LVOUT
STEP 4:
Connect the antenna to the SMA connector
•
Overall efficiency from the antenna to the storage element:
