4.3.2 Transmitter Module (TX)
The MASTR V TX module series EA-555008 provides a highly stable +6 dBm RF output to drive the
High Power Amplifier module. The MASTR V TX module uses a Direct Digital Synthesizer (DSS)
which optimizes the modulation characteristics of the TX module. DSS can digitally create a precision
waveform or modulation scheme from a single on-board oscillator. This capability makes the MASTR V
TX module one of the most versatile transmitter modules in the North American Land Mobile Radio
(LMR) and European Professional Mobile Radio (PMR) marketplace.
