NOTES:  
1.  
2.  
3.  
Unless noted otherwise, all specifications apply over temperature range.  
Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc.  
Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is dependent on PCB layout and external  
impedance matching design.  
4.  
5.  
6.  
"LRIP" or "L" after the part number indicates "low rate initial production" and "ENG" or "E" indicates "engineering prototypes."  
The design, manufacturing process, and specifications of this filter are subject to change.  
Either Port 1 or Port 2 may be used for either input or output in the design. However, impedances and impedance matching may vary between Port 1 and Port  
2, so that the filter must always be installed in one direction per the circuit design.

US and international patents may apply.
