CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1.
Unless noted otherwise, all specifications apply over the operating tem-
perature range with filter soldered to the specified demonstration board
with impedance matching to 50
Ω
and measured with 50
Ω
network ana-
lyzer.
Unless noted otherwise, all frequency specifications are referenced to the
nominal center frequency, fc.
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.
