General Description
Pin Configuration
The 885070 is a high-performance, high power Bulk
Pin No. Label
Acoustic Wave (BAW) band-pass filter with extremely
9 Input
steep skirts, simultaneously exhibiting low loss in the
6 Output
WiFi band and high rejection in the band-edge and
adjacent LTE /TD-LTE bands. 1,2,3,4,5,7,8,10 Case Ground
The 885070 enables coexistence of WiFi and LTE
signals within the same device or in close proximity to
one another. Its unique power handling capability
allows for implementation into high performance high
power access points and small cell base stations.
The 885070 uses common module packaging
techniques to achieve the industry standard 1.7 x 1.32
x 0.46 mm footprint. The filter exhibits industry leading
power handling capabilities up to 1W.

Notes:
1. In production, devices will be tested at room temperature to a guard-banded specification to ensure electrical compliance
over temperature.
2. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing
tolerances.
3. Only at 25C.
4. Data is the integrated value of the linear s-parameter over a 19 MHz range in the indicated band at the specified
temperature.
5. Data is the integrated value of the linear s-parameter over a 5 MHz range at the specified temperature.
6. An external impedance matching network with 2 % tolerance will be necessary to achieve the stated specifications.
7. This is the optimum impedance in order to achieve the performance shown.
