fixed, normally
at
about
470 kHz or 10.7
MHz. Ceramic filters combine good
i.f.
tuning with small size.
Another type
of
filter
now
used
in i.f.
amplifiers
is the
surface-
acoustic-wave (s.a.w.) device.
By
means
of a
transducer*
the
signal
is transmitted along
the
surface
of a
piezo-electric material
in the
form
of
minute deformations
of the
surface.
By
shaping
the
surface
suitably
the
effect
of a
bandpass
(or
other type
of)
filter
can be
achieved
and the
signal
can be
recovered
by use of
another
transducer. Extremely small robust filters with stable characteristics
can
be
produced
by
this means.
