This configuration refer to a Combiner which makes use of Bandpass Mask Filters (6, 7, and 8-Pole) , and consequently Filters in the Transmitters are either not present or removed.
This approach has several advantages:
- Highest system efficiency
- Transmitters are completely frequency-agile (no built-in Filters)
- Adjacent Channel combination
- Constant impedance provides best Transmitter working conditions (Balanced Combiners)
