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
net-
work analyzer.
2. Unless noted otherwise, all frequency specifications are referenced to
the nominal center frequency, fc.
3. 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 Applica-
tion Note No. 42 for details.
4. "LRIP" or "L" after the part number indicates "low rate initial produc-
tion" and "ENG" or "E" indicates "engineering prototypes."
The design, manufacturing process, and specifications of this filter
are subject to change.
6. 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.
7. US and international patents may apply.
