1. Unless noted oth erwis e, all spec ifications apply ov er the operating temperatur e range with filter soldered to the specified demons trat ion board with imped ance
match ing to 50 Ω and measured with 50 Ω network analyz er.
2. Unless noted otherwise, all frequenc y specifications are referenced to the nominal center frequen cy, fc .
3. Rejection is measured as attenuation below the minimum IL point in the passband. Rejec tion in final user application is dependent on PCB layout and e xt ernal
impedance matching des ign. See Application Note No. 42 for details.
4. The desi gn, manufact uring process , and specifications of this filter are subject to change.
5. US and international patents may apply.
