production of cavity filters covers the VHF e UHF frequency ranges,
with special emphasis with the 30 MHz to 1.5 GHz range. Our 10+ year
experience acquired in this field allows us to manufacture filters which
are highly selective and extremely reliable: their operation has been
field tested under any environmental and thermal condition.
has been individually designed, manufactured and calibrated to meet
the specific needs of the customer, on order to attain the best achievable
results. Among the features available for each model, we would like
to stress the unique adjustment system of the insertion loss, essential
for minimizing the power loss vs. the need to minimize the noise.
special range of our products deals with the "TT" filters, whose
height is up to 70% less than standard models, suitable wherever there
is a very specific space requirement (rack - mobile link, etc.) and minimally
lesser performances (5-10%) with respect to the standard models. The "TT"
models are manufactured only upon request and their cost is related to
the physical parameter: for this reason the catalog contains just a few
of such models. The triplexers are not listed in the catalog, since the
resonance curves may vary in relationship to the three transmission/reception
frequencies. Generally, however, it is possible to rate an insertion loss
of about 1.5 dB and attenuations higher than 90 dB for shifts equal to
the attenuation found in the diplexers.
