As for electrical performance, this product, which
consists of 4 elements, provides stop band attenuation
equivalent to that of our previous 6-element product.
The input/output impedance characteristics are also
equivalent to those of the previous product, and
spurious responses in the vicinity of the passing band
can now be eliminated. This allows mobile
