Notes:

shown above and subject to change or obsolescence without

notice.

The frequency f_Cis defined as the midpoint between the 3dB

frequencies.

All equipment designs utilizing this product must be approved by

the appropriate government agency prior to manufacture or sale.

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.

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.

For questions on technology, prices and delivery please contact

our sales offices or e-mail sales@vanlong.com.

Unless noted otherwise, specifications apply over the entire

specified operating temperature range.

The specifications of this device are based on the test circuit
