885071 2.4 GHz WLAN/BT LTE Co-Existence Filter General Description The 885071 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 band-edge & near-in rejection. The 885071 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 implantation into access points small cell base The 885071 uses common module packaging techniques to achieve the industry standard 1.4 x 1.2 x CSP-5CT package: 1.4 x 1.2 x 0.46 mm 0.46 mm footprint. The filter exhibits excellent power Handling capabilities.

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. Data is the integrated value of the linear s-parameter over 19 MHz window for the indicated band at the specified temperature. 4. Duration in ns between the maxima and the point 40 dB below the maxima. 5. Data is the integrated value of the linear s-parameter over 5 MHz range at the specified temperature. 6. An external impedance matching network with 3 % tolerance will be necessary to achieve the stated specifications. 7. This is the optimum impedance in order to achieve the performance shown.
