4.5 RF Output Power
The DA14AVDDECT module is fully tested and RF output power is trimmed during production. There
is a temperature compensation algorithm implemented in each AVD firmware that maintains the
target output power over temperature range. The default target output power is 22 dBm for EU and
Japan DECT and 20 dBm for US DECT. Decreasing the target output power is possible by human
readable settings via EEPROM.
5 Software Overview
There are three different projects and six different project profiles for the module:
○ Audio Data (AD) Tour Guide – FP and PP profile
○ Audio Data (AD) Public Address – FP and PP profile
○ Voice Data (VD) Stack – FP and PP profile
5.1 Terminology
Audio Data (AD) stacks are referred by the software as WAM (Wireless Audio Module). Voice Data
(VD) stack is referred by the software as CVM (Cordless Voice Module).
