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.
Rejection is measured as attenuation below the minimum IL point in the pass-
band. Rejection in final user application is dependent on PCB layout and exter-
nal impedance matching design. See Application Note No. 42 for details.
The design, manufacturing process, and specifications of this filter are subject
to change.
