performed by the system DSP, giving the MASTR V receiver the flexibility needed in current and future
LMR communications systems.
All bands of MASTR V RX modules share common design features and meet stringent receiver
specifications including the following:
High intercept point.
Low noise figure.
110.2 MHz IF chosen for all bands of the MASTR V.
Automatic Level Control.
Built-in 10 MHz reference; switchable to external reference derived from the baseband module
(which is compatible with an external frequency standard used for Simulcast).
High side LO injection for superior noise performance .
Built-in hardware diagnostics (voltage supplies, PLL Lock).
Built-in analog FM test mode.
Raw IQ data is sent to the BaseBand Processor module for demodulation.
