The UL signals are received by the integrated
antenna (MR2003B) or the external antenna
(MR2003D) and are then fed to the duplexer. After the
duplexer a pre-selection of the frequency is made.
Then the signals are converted down to IF by means
of a mixer. An IF filter provides the selectivity against
other frequencies.
The signals are re-converted and are amplified in an
amplifier that provides the output power. The signals
are then fed to the donor antenna via the duplexer.
In this link, an ALC is provided, too.
