CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
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 Application 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.
