match ing to 50 Ω and measured with 50 Ω network analyzer.
2. Unless noted otherwise, all freque ncy specifications are referenced to the nominal center frequency, fc.
3. Rejection i s measured as atten uation below the minimum IL point in th e pas sband. Rejecti on in final user ap plication is dependent on P CB l ay out a nd ext erna l
impedance matching des ign. See Application Note No. 42 for details.
4. Part to part absolute delay meas urement records the absolute delay mean across 1 dB passban d.
5. "LRIP" or "L" after the part number indicates "low rate initial production" and " ENG" or "E" indicates "engineering prototypes.”
6. The desi gn, manufact uring process, and specifications of this filter are subject to change.
7. Eith er Port 1 or Por t 2 may be used f or either inpu t o r ou tp ut in t he d esign. Ho wever, impedanc es and imped ance matchi ng ma y vary bet ween Por t 1 and Por t
2, so that the filter must always be installed in one dir ection per the circuit design .
8. US and international patents may apply.
