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.

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 Application Note No. 42 for details.

4.

"LRIP" or "L" after the part number indicates "low rate initial production" and "ENG" or "E" indicates "engineering prototypes."

5.

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.
