The specifications of this device are based on the test circuit shown
above and subject to change or obsolescence without notice.
Unless noted otherwise, all measurements are made with the filter
installed in the specified test fixture that is connected to a 50Ω test
system with VSWR ≤ 1.2:1. The test fixture L and C are adjusted for
minimum insertion loss at the filter center frequency, fC. Note that
insertion loss, bandwidth, and passband shape are dependent on
the impedance matching component values and quality.
All equipment designs utilizing this product must be approved by the
appropriate government agency prior to manufacture or sale.
Our liability is only assumed for the Surface Acoustic Wave (SAW)
component(s) per se, not for applications, processes and circuits
implemented within components or assemblies.
