The multi-program models are designed in one modular mechanical structure which can house up to two identical band pass filters, type M1F4, in Double Bridge Configuration.
They are composed by two different Double Cavity Filters and two Hybrid Couplers, including a Narrow band and wide band input lines.
On request, with the same technology, up to eight different transmitters can be combined to a common transmission antenna.
A directional coupler is assembled at the output of the combiner, which delivers two reflected and direct monitories at a preset level of -50 Db.
