General Description Pin Configuration
Pin # SE Description
857145 is a RF filter for wireless infrastructure
2 Input
applications. This filter was specifically designed for
5 Output
filtering in the digital pre-distortion path in Base Station
1,3,4,6 Case Ground
applications. This filter is designed in a 3x3mm hermetic
package and is part of our wide portfolio of RF filters in
the same package.
Low insertion loss, coupled with high attenuation and
excellent power handling, makes this filter a natural choice Ordering Information

Notes:
1. All specifications are based on the TriQuint schematic shown on page 3.
2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature.
3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances.
4. Typical values are based on average measurements at room temperature.
5. Variation is defined as the total peak to peak variation over the defined frequency range.
6. To be measured only during engineering development.
7. Temperature Drift specification is defined on Page 3 and is guaranteed by design and wont be measured in production
8. Relative to maximum insertion loss at center frequency.
9. This is the optimum impedance in order to achieve the performance shown.
