Hybrid Combiner in MTS 2

The Hybrid Combiner is a part of the transmitter path in the RF Distribution System. The Hybrid
Combiner provides very reliable combining of up to two transmitters. The Hybrid Combiner
has no limitations in respect to channel spacing of the TX channels, however for frequency
planning and interference reasons at least 50kHz is recommended.

Figure 7-9 Hybrid Combiner

The TX signals from two Base Radios are attached to the respective Hybrid Combiner inputs. The
combined signal at the Hybrid Combiner outport port is then applied to the Duplexer.
The Hybrid Combiner contains one printed circuit board.
