Notes:
1. The frequency f_C is defined as the midpoint between the 3dB
frequencies.
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.
3. Unless noted otherwise, specifications apply over the entire
specified operating temperature range.
4. Frequency aging is the change in f_C with 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.
5. 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].
6. The specifications of this device are based on the test circuit
shown above and subject to change or obsolescence without
notice.
7. All equipment designs utilizing this product must be approved by
the appropriate government agency prior to manufacture or sale.
8. 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.
