1. Unless noted ot herwis e, all s pecif icat ions app ly over th e ope rati ng temp erature rang e with filter sol dered to the specifi ed demonstr ation bo ard wit h impedan ce
matching t o 50 Ω and measured with 50 Ω network analyzer.
2. Unless noted otherwise, all frequency spec ifications are referenced to the nominal center frequency, fc.
3. Rejection is measured as attenuat ion below the mi nimum IL point in the pas sband. Rejection in final user app lication is depende nt on PCB layou t and external
impedance mat ching 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 filt er are subject to c hange.
6. Either Port 1 o r Po rt 2 may be used f or eith er in put or out put in t he design . Ho wever, impedances and imped ance ma tchin g may va ry betwe en P ort 1 an d Po rt
2, so that the filter must always be installed in one direction per the circu i t design.
