Notes:  
1.  
Unless noted otherwise, all specifications apply over the operating temperature  
range with filter soldered to the specified demonstration board with impedance  
matching to 50 W and measured with 50 W network analyzer.  
Unless noted otherwise, all frequency specifications are referenced to the nom-  
inal center frequency, fc.  
Rejection is measured as attenuation below the minimum IL point in the pass-  
band. Rejection in final user application is dependent on PCB layout and exter-  
nal 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."  
6.  
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.
