Unless noted otherwise, all specifications apply over the operating temperature with filter matched to 50 ohms and measured with a 50 ohm network analyzer. 2. Rejection levels are measured from the minimum loss in the passband. 3. All frequency specifications are referenced to the nominal center frequency, Fc.
