shown above and subject to change or obsolescence without

notice.

frequencies.

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, f_C. 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.

Unless noted otherwise, specifications apply over the entire

specified operating temperature range.
