Filters are usually manufactured in
brass but filters in beryllium copper are also possible.
SURFACE TREATMENT
The corrosion treatment is made
through Silver-plating.
ELECTRICAL CHARACTERISTICS
Regardless of the number of cavities
(3, 4 or 5), the maximum value of V.S.W.R is 26dB and the insertion loss
goes from a minimum of 0.8dB to a maximum of 2.7dB, obviously it depends on
the kind of filter chosen. In the same way, the damping to 70MHz, is
included between 24 and 65 dB (it depends on the number of cavities).The filters can be
supplied with inlet and outlet having the following combinations:
flange/flange, flange/SMA or SMA/SMA.
MODIFICATIONS ON CUSTOM MADE.
In
the following pages you will find the list of filters usually requested,
otherwise it is also possible to manufacture these products on custom-made
through a few modifications to the working frequency and to the different
kind of inlet and outlet.
