General Description
885017 is a high-performance, high-power Bulk Acoustic
Wave (BAW) bandpass filter with extremely steep skirts,
simultaneously exhibiting low loss in the WiFi band & high
near-in rejection in the 2.3GHz & 2.6GHz
WiMAX/LTE/TD-LTE bands.
885017 is specifically designed to enable coexistence of
WiFi and WiMAX/LTE signals within the same device or in
close proximity to one another.
885017 uses advanced and inexpensive packaging
techniques to achieve an industry-leading 1.4 x 1.2 x 0.46
mm package. The filter exhibits excellent power handling
capabilities.
885017 is referenced on multiple designs with the leading
WiMAX chipset makers

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. Typical values are based on average measurements at room temperature
4. Relative to zero dB
5. This is the optimum impedance in order to achieve the performance shown
6. These bands fall on the filter transitions, thus the typical attenuation/loss values given are prone to high variability
7. Average attenuation level over the band
