2.5.3 Atlas Mobile Transmitters
Atlas Mobile transmitters can be configured with one PA cabinet with 2 to 8 PA modules
or two or more PA cabinets and single or dual exciters.
2.5.3.1 Atlas Mobile Transmitter - 1 PA Cabinet, 2 Exciters
The single cabinet Atlas Mobile transmitter system is shown in Figure 2-3. It has dual
exciters with the RF sample feedback connections shown. Samples for each exciter are
provided by two-way, zero-phase splitters in each feedback sample line.
The feedback signals at the exciter inputs should be padded to yield 0 dBm at the highest
expected transmitter output power. The maximum input range is -30 to 0 dBm.
