weighted filter.  Test circuit Figure 3.  The parameters listed below are tested using automatic test equipment to assure consistent electrical
characterristics.  The limits do not represent the ultimate performance limits of the device.  Use of an optimized RF layout will improve many of
the listed parameters.
