!INTRODUCTION
Murata has continued research on surface acoustic wave
filters since 1970. In 1976 we offered for sale our first
surface acoustic wave filter to be used in the IF of high-
fidelity FM tuners. Then, we successfully developed and
offered for sale the surface acoustic wave filter for the video
IF of color television sets.
Now surface acoustic wave filters have been parts
indispensable to electronic circuits of video equipments and
telecommunication equipments such as TV/VCR.
Murata has successfully put surface wave filters
incorporating ZnO thin film into series. It is realized to be in
resin molded small package (SIP), and stable temperature
characteristics.

The basic configuration of a SAW filter is two IDTs (comb
type electrode) on the piezoelectric substrate.
The first IDT connected to the signal source generates a
surface acoustic wave, which propagates along a substrate
surface to the second IDT, which transforms SAW energy
into electrical voltage on a load connected to the IDT.
This is shown in the Fig.-1.

Frequency characteristics of the IDTs can be calculated by
means of impulse model. In case of Normal IDT which has
a constant pitch and a constant overlap, the IDT and the
corresponding impulse is shown in Fig.-2 below.

!NOTICE
¡Do not apply DC voltage between the each terminal.
¡Washing filter is not acceptable due to unsealed
construction.
¡Filter might be damaged when an excessive stress was
applied.
Impulse
¡Matching condition should be evaluated well to perform
stable electrical characteristics which are specified.
¡We can not warrant against defects caused by any use of
the filter which deviates from the intended use as described
in this catalog. Please contact us for any other
characteristics, using conditions or application to the device
which need to be extremely reliable.
Fig.Y2 IDT and the corresponding impulse
When a voltage is fed to the IDT, the direction of the voltage
is the positive-negative-positive-negative at λ 0/2 interval.
The voltage is then subjected to expansion and shrinkage of
substrate by the piezoelectric effect. One impulse pair of
adjacent positive and negative polarities is corresponding to
one electrode pair.
When the wavelength of the surface acoustic waves
generated by each impulse is equal to the electrode pitch
λ 0, we get maximum SAW energy.
When wave velocity is V, electrode pitch is λ 0, number of
electrode pair is N, then frequency characteristics of normal
IDT can be calculated by the equations shown below.

Series
CATV 70/200Z
The Best SAW Filter Choice for CATV Miniaturizing and
Adding Efficiency
For the first time in history of the electronic industry, mass
production of SURFACE ACOUSTIC WAVE FILTERS
incorporating zinc oxide (ZnO) thin film has begun.
In addition, MURATA has begun commercial production of a
wide variety of surface acoustic wave filters for CATV use.
