GF82.62-P-3105-03R Antenna Amplifier Module, Design







The following functions are integrated into the left antenna amplifier module (A2/64) and right antenna amplifier module (A2/65) (see block diagram):
^ Filter and amplifier with diversity system for the FM signals (FM1 up to FM4) of the windshield FM antennas (on vehicles with Vehicle Information Communication System (VICS) (Japan), FM3 discontinued),
^ Demodulator for the signals for controlling the radio remote central locking (RRCL [FZV]),
^ Filter and amplifier for the TV signals of the windshield antennas,
^ Filter for the AM signals that come from the rear shelf antenna amplifier (A2/67).

In the rear window antenna amplifier module (A2/12) and in the rear shelf antenna amplifier (A2/67) , amplifiers for AM signals are integrated.
In addition, a selection switch for the selection of the received AM signals is installed in the rear shelf antenna amplifier (A2/67) , depending on the Vario roof position.
