See note 4  
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.  
2.  
3.  
4.  
5.  
Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc.  
"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.
