"lrip" or "l" after the part number indicates "low rate initial production" and "eng" or "e" indicates "engineering prototypes.? 6. the design, manufacturing process, and specifications of this filter are subject to change. 7. 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. 8. us and international patents may apply. 9. electrostatic sensitive device. observe precautions for handling. 10. values of l&c are starting point values base upon rfm demonstration board. final customer values may vary. 140 nh 50 saw filter 4.2 pf 4.6 pf top view pin 5 pin 10 50 all others 130 nh
