Delta Meccanica produces a complete line of FMRadio band pass filters.
Band Pass filters sometimes have an irreplaceable employee in many broadcasting systems. The main purpose of these devices is cutting off all the
frequencies except the one tuned on he filter,minimising the insertion loss.
Basic configuration of our filters (except the type for low power) consists of two cylindrical cavities,
interconnected by an inductive coupling.
The above mentioned cylindrical geometry improves the R.F. efficiency, and thermal stability, and allows to add, in modular way, other cavities to the basic configuration, to have filters with three or even more cavities, when it is necessary to have a tighter selectivity, but it is also necessary to consider that, more cavities means greater insertion loss.
Our equipments are thermal compensated, and all the filter's components have surface treatment, to
improve the R.F. efficiency and reliability in the lifetime.
Special arrangement, according to Customer's requirements, can be designed.
For their thermal efficiency, our devices aren't in want of forced cooling or radiators.
