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.
