All signals in Table 1 except RF, VCC and GND are connected directly to the corresponding signals on
the ZW0201 Z-Wave Single Chip on the ZM2102 Z-Wave Module. A detailed description of these signals
is given in the ZW0201 Z-Wave Single Chip datasheet [1].
1.3
1.3.1
The ZM2102 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 ZW0201 is a single ended input/output that is internally matched to 50 ohm.
1.3.2
The ZM2102 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 ZM2102 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
