Notes:

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 Ω and measured with 50 Ω

network analyzer.

2. Unless noted otherwise, all frequency specifications are referenced

to the nominal center frequency, fc.

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.

4. The design, manufacturing process, and specifications of this filter

are subject to change.

5. Tape and Reel Standard Per ANSI / EIA 481.

6. US and international patents may apply.

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

trademarks of RF Monolithics, Inc.

Electrostatic Sensitive Device. Observe precautions for handling.
