CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.  
Notes:  
1.  
Unless noted otherwise, all specifications apply over the operating temper-  
ature range with filter soldered to the specified demonstration board with  
impedance matching to 50 Ω and measured with 50 Ω network analyzer.  
Unless noted otherwise, all frequency specifications are referenced to the  
nominal center frequency, fc.  
Rejection in final user application is dependent on PCB layout and  
external impedance matching design. See Application Note No. 42 for  
details.  
"LRIP" or "L" after the part number indicates "low rate initial production"  
and "ENG" or "E" indicates "engineering prototypes."  
5.  
6.  
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.
