CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1.
Unless noted otherwise, all specifications apply over the operating temper-
ature range with filter soldered to the specified demonstration board with
impedance matching to 50 and measured with 50 network analyzer.
Unless noted otherwise, all frequency specifications are referenced to the
nominal center frequency, fc.
and "ENG" or "E" indicates "engineering prototypes."
5.
6.
The design, manufacturing process, and specifications of this filter are
subject to change.
2.
3.
Either Port 1 or Port 2 may be used for either input or output in the design.
However, impedances and impedance matching may vary between Port 1
and Port 2, so that the filter must always be installed in one direction per
the circuit design.
US and international patents may apply.

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.
