1. Unless note d otherwis e , all spe cifica tions apply over the operati ng t emperat ure ra nge with f ilter s oldered t o t he specif ied demonstra tio n boa rd with imped ance
match ing to 50 Ω and measured with 50 Ω network analyzer.
2. Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc.
3. Rejection is measure d as at tenuat io n below the minimum IL po int in the p ass band. Reject ion in final us er applic atio n is depe nde nt o n PCB layo ut and e xtern al
impedance matching design. See Application Note No. 42 for details.
4. The desi gn, manufact uring process, and specifications of this filter are subject to change.
5. Eith er Port 1 or Port 2 may be used fo r eith er input or out pu t in th e design. However, impedances and impedan ce matchin g may v ary bet ween Po rt 1 and Port
2, so that t he filter must always be installed in one direction per the circuit design.
