General Description
856705 is a general purpose Uplink filter for Band 2. 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
excellent 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. Relative to maximum insertion loss
7. This is the optimum impedance in order to achieve the performance shown
