Notes:

The frequency f_Cis defined as the midpoint between the 3dB

frequencies.

Turnover temperature, T₀, is the temperature of maximum (or

turnover) frequency, f₀. The nominal frequency at any case

temperature, T_C, may be calculated from: f = f₀[1 - FTC (T₀- T_C)²].

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.

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.

Unless noted otherwise, specifications apply over the entire

specified operating temperature range.

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.

Frequency aging is the change in f_Cwith time and is specified at

+65°C or less. Aging may exceed the specification for prolonged

temperatures above +65°C. Typically, aging is greatest the first

year after manufacture, decreasing in subsequent years.
