Receiver Module (RX)
The MASTR V Receiver (RX) modules, model EA-555007, are dual-IF conversion receivers. The RX
modules are currently available in the 700/800 dual band, model EA-555007-011, with EA-555007-002
covering the 150-174MHz VHF band split.
The receiver uses a Sigma-Delta analog to digital converter to process the incoming IF signal. The output
of the analog-to-digital converter is a complex pair of I/Q baseband digital signals. The MASTR V RX
module supports a wide range of modulation waveforms required for current and next generation public
safety two-way radio communications.
After IF filtering and down-conversion, received signals are digitized into I and Q information and sent to
the Baseband Processor module via the backplane Ethernet. The Baseband Processor module provides
the narrow channel filtering and demodulation. The narrow channel filters and digital demodulation is
