Observe precautions for handling! 1. Unless noted otherwise, all measurements are made with the filter installed in the specified test fixture that is connected to a 50 Ω test system with VSWR ≤1.2:1. The test fixture L and C are adjusted for minimum insertion loss at the filter centre frequency, f C. Note that insertion loss, bandwidth, and passband shape are dependent on the impedance matching component values and quality. Unless noted otherwise, specifications apply over the entire specified operating temperature range. The specifications of this device are based on the test circuit shown above and subject to change or obsolescence without notice. 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. 2. 3. 4. 5.
