General Description
The 856678 is a Surface Acoustic Wave (SAW) based filter
suitable for LTE Band 1 Uplink.
856678 is specifically designed to meet the high
performance expectations of insertion loss and rejection for
LTE downlink systems under all operating conditions.
This filter is housed in a compact, industry standard 3 x 3 mm
footprint.
Low insertion loss, coupled with high attenuation makes this
filter an ideal choice for Base Station Applications.
This filter is part of TriQuint’s wide portfolio of RF filters.

Notes:
1. All specifications are based on the test circuit shown below.
2. Production test is performed at room temp. to a guard-banded specification to ensure electrical compliance over temperature.
3. Electrical margin has been built into the design to account for variation due to temperature drift and manufacturing tolerances.
4. Typical values are based on average measurements at room temperature
5. This is the optimum impedance in order to achieve the performance shown.
