Notes:  
1.  
2.  
The frequency fC is defined as the midpoint between the 3dB  
frequencies.  
4.  
The specifications of this device are based on the test circuit  
shown above and subject to change or obsolescence without  
notice.  
Unless noted otherwise, all measurements are made with the filter  
installed in the specified test fixture that is connected to a 50test  
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.  
5.  
6.  
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.  
3.  
Unless noted otherwise, specifications apply over the entire  
specified operating temperature range.
