1.4.1
The ZM3102N Z-Wave Module is equipped with a SAW filter that rejects the unwanted frequencies both
in receive and transmit operations.
The RF input/output on the ZW0301 is a single ended input/output that is internally matched to 50 ohm.
1.4.2
The ZM3102N Z-Wave Module is using an antenna placed on the Application Module, the matching of
the external antenna to 50 ohm (SAW filter impedance) must be made on the Application Module.
As the ZM3102N Z-Wave Module is integrated into various products, different types of antennas can be
implemented to get the best RF performance, i.e. range and reliability. In [4], a good overview of the
different antennas is given as well as their pro’s and con’s. In the case the antenna is not 50ohm a
matching network must be implemented between the ZM3102N Z-Wave Module and the antenna. The
matching network can for example be a “pi” or a “T” structure as shown in Figure 4.
1.5
The ZM3102N Z-Wave Module is programmed using the SPI interface and the RESET_N signal. The
programming procedure of the ZW0301 flash is identical to the programming procedure of ZW0201. For
detailed programming instructions see [2] and recommended programming tool(s) see [3].
