This TX multiplexer handles very high mean power and combines four transmitters toward a single antenna.

Several high selectivity filters are parts of it.

This system includes monitoring with remote control.



Up and Down Converter

Deti point out a range of Up & Down converters for point-to-point or point-to-multipoint transmission. Those compact and rugged receivers-transmitters suit the needs of wireless broadband communications for offshore or shipping connections or for white area coverage. It especially fits in with the use for Ku and Q band links. It is also compatible with a wide variety of modems (it bears modulations till 16 QAM for several frequency band).  Available datasheet on request.


DETI acts on any part of product life cycle: design, development, prototyping, industrialization, environmental qualification, series manufacture, tests and trials and trough life support.

We can take the responsibility for the overall process or step in on a more limited basis for specialized services according your needs.
