2.18.2.4 Non Rechargeable battery
This is the less recommended solution.
VCC-RTC
(2.75 V max)
Diode (Ex : BAS16)
10
Ex : CR2016
(VARTA)
Estimated range with 85 mAh battery: 4000 h minimum
Note: The “non rechargeable battery” is always active, except when the
module is ON.
2.19 RF interface
The impedance is 50 0Ohms nominal and the DC impedance is 0 Ohm.
2.19.1 RF connection
Two land patterns set on the PCB support the RF connection which can be
used by the application through spring contacts or a soldered RF cable.
There are two possible ways to connect an antenna to the module:
•
The antenna can be directly connected to the module on the "Antenna pad"
by using a spring contact.
•
The antenna can be connected to the module through a coaxial cable. The
coaxial cable is connected to both the "Round pad" and the "Ground pad".
Since no standard spring contact is available for WISMO Quik Q2403 Series,
this solution requires a specific part to be developed.
The soldered solution will preferably be based on a RG178 coaxial cable with
the following stripping and mounting guidelines:
