General Description
Uplink filter combining bands 13 and 14 for general
purpose wireless applications. This filter was specifically
designed in a 3x3mm hermetic package for base station
applications and is part of our wide portfolio of RF filters
in the same package.
Low insertion loss, coupled with high attenuation and good
power handling, makes this filter a natural choice for our
customers uplink RF filtering needs.

Notes:
1. All specifications are based on the TriQuint schematic for the main reference design 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. Describes the total variation over the defined frequency range
6. This is defined as the worst difference between a peak and adjacent valley within defined frequency points
7. Relative to passband loss at center frequency
8. This is the optimum impedance in order to achieve the performance shown
