1. Unless not ed othe rwise, all spe cificat ion s appl y ove r the op era ting t emper-
ature range with filter soldered to the specified demonstration board with
impedance matching to 50 Ω and measured with 50 Ω network anal yz e r.
2. Rejection is measured as atte nuation 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 det ails.
3. The design, manufacturing process, and specifications of this filter are
subject to change.
4. US and international pat ents may apply.
