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.

8. RFM, stylized RFM logo, and RF Monolithics, Inc. are registered

trademarks of RF Monolithics, Inc.

10. Electrostatic Sensitive Device. Observe precautions for handling.

4. "LRIP" or "L" after the part number indicates "low rate initial produc-

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