1. Unless noted othe rwise, all specifica tio ns apply ov er the opera tin g tempera tu re range with f ilter so lder ed to the spec ified d emons tr ation bo ard with i mpeda nce
matching to 50 Ω and measured with 50 Ω network analyzer.
2. Rejectio n is measured as attenuation below the minimum IL point in the passb and. Rejection in final u ser application is dependent on PCB lay out and ex terna l
impedance matching des ign. See Application Note No. 42 for deta ils.
3. The desi gn, manufact uring proce ss, and specifications of this filter are subject to change.
4. Tape and Reel Standard ANSI / EIA 481.
5. Either Port 1 or Port 2 may be used for either inpu t or out put in the design. However, impedances and impedance matching may vary be tween Port 1 and Port
2, so that the filter mus t always be inst alled in one direc tion per the ci rcuit design .
