Notes:  
5. The design, manufacturing process, and specifications of this filter  
are subject to change.  
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.  
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 net-  
work analyzer.  
2. Unless noted otherwise, all frequency specifications are referenced to  
the nominal center frequency, fc.  
7. US and international patents may apply.  
3. 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. See Applica-  
tion Note No. 42 for details.

9. ©Copyright 1999, RF Monolithics Inc.  
10. Electrostatic Sensitive Device. Observe precautions for handlin

tion" and "ENG" or "E" indicates "engineering prototypes."
