1. Unless noted otherwise, all specifications apply o ver the operating temperatur e range with filter s oldered to the specified demons trat ion board with imped ance
match ing to 50 Ω and measured with 50 Ω network analyzer.
2. Unless noted otherwise, all frequenc y specifications are referenced to the nominal center frequency, fc.
3. Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is dependent on PCB layout and external
impedance matching design. See Application Note No. 42 for details.
4. The desi gn, manufact uring process, and specifications of this filter ar e subject to change.
5. US and international patents may apply.
