Notes:  
1.  
2.  
The frequency fC is defined as the midpoint between the 3dB  
frequencies.  
5.  
6.  
Turnover temperature, T0, is the temperature of maximum (or  
turnover) frequency, f0. The nominal frequency at any case  
temperature, TC, may be calculated from: f = f0 [1 - FTC (T0 - TC)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, fC. 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.  
7.  
8.  
All equipment designs utilizing this product must be approved by  
the appropriate government agency prior to manufacture or sale.  
3.  
4.  
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 fC 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.
