General Description
The 885070–A is a high-performance, high power Bulk
Acoustic Wave (BAW) band-pass filter with extremely
steep skirts, simultaneously exhibiting low loss in the
WiFi band and high rejection in the band-edge
frequencies and adjacent LTE /TD-LTE bands.
The 885070–A also 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–A uses common module packaging
techniques to achieve the industry standard 1.7 x 1.32 x
0.46 mm footprint. The filter has met stringent
automotive requirements derived from AEC-Q200
standard and is suitable for use in infotainment and
telematics applications.

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. This is the typical performance at only 25 °C.
4. Data is the integrated value of the linear s-parameter over a 19 MHz window 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.
