Hybrid Combiner

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 50 kHz is recommended.
