CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.

Notes:

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 Ω and measured with 50 Ω network analyzer.

Unless noted otherwise, all frequency specifications are referenced to the

nominal center frequency, fc.

and "ENG" or "E" indicates "engineering prototypes."

The design, manufacturing process, and specifications of this filter are

subject to change.

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.

"LRIP" or "L" after the part number indicates "low rate initial production"
