"lrip" or "l" after the part number indicates "low rate initial production" and "eng" or "e" indicates "engineering prototypes." 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. 7. us and international patents may apply. 8. rfm, stylized rfm logo, and rf monolithics, inc. are registered trademarks of rf monolithics, inc. 9. ?copyright 1999, rf monolithics inc. caution: electrostatic sensitive device. observe precautions for handling. notes:
