Notes:
1.
Unless noted otherwise, all specitication apply over the operating temperature range with filter soldered to the specified demonstration board with
impedanced matching to 50
network analyzer.
Unless noted otherwise, all frequency specitications 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 oon PCB layout
and external impedance matching design. See Application Note No. 42 for details.
“LRIP” or “L” after the part number indicates “l(fā)ow rate initial production” 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.
Electrostatic Sensitive Device. Observe precautions for handling.
