1. Unless not ed othe rwise, all spe cificat ion s appl y ove r the op era ting t emper-

ature range with filt er soldered to the specified demonstration board with

impedance matching to 50 Ω and measured with 50 Ω network an a l y zer.

2. Unless noted otherwise, all frequency specificat ions are referenced to the

nominal center frequency, fc.

3. Rejection is measured as attenuation below the minimum IL point in the

passband. Rejectio n in final user application is dependent on PCB layout

and external impedance matching design. See Application Note No. 42

for det ails.

4. "LRIP" or "L" after the part number indicates "low rat e initial production"

and "ENG" or " E" indicates "engineering prototy pes."

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

subject to change.

6. Either Port 1 or Port 2 may be us ed for ei ther input or output in the des ign.

However, impedance s and impeda nce mat chi ng may vary betwe en Port 1

and Port 2, so that the filter must always be installed in one direction per

the circ uit design.

7. US and international patent s may apply.

8. RFM, stylized RFM logo , and RF Monolithics , I nc. are registered
