Unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified d emonstration board with impedance matching to 50 Ω and measured with 50 Ω network analyzer. 2. Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is depen dent on PCB layout and external impedance matching design. See Application Note No. 42 for details. 3. The design, manufacturing process, and specifications of this filter are subject to change. 4. Tape and Reel Standard ANSI / EIA 481. 5. 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. 6. US and international patents may apply. 7. RFM, stylized RFM logo, and RF Monolithics, Inc. are registered trademarks of RF Monolithics, Inc.
