The RF sub module provides the necessary pre-conditioning for amplifying and
filtering the RF signal at 2.4-2.5GHz. The module contains the RF power amplifier
and the low noise amplifier, with the necessary RF pre-selector filter.
The amplifier provides the necessary RF output power. Two identical RF sub-
modules are implemented in the SMT349 module.
