[W-MBUS] “There is something I do not understand. In the 169 Mhz it is allowed to transmit at 500mW or +27dBm. This is specified by the module if a power supply of 5V is used for the power amplifier. However , if you want to transmit at +27dBm this means a Vpp of approximately +14.1 Volt . Is there a DC-DC convertor on board of the module ? “

The module transmit +27 dBm (500mW) when transmitter part is powered with 5V. No additional DC-DC externally is needed.
