885128 2.4 GHz WLAN/BT LTE Co-Existence Filter General Description The 885128 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 near-in rejection in the approximate LTE bands. 885128 is specifically designed to enable coexistence of WiFi and LTE signals within the same device or in close proximity to one another. The 885128 uses common module packaging techniques 1.1 X 0.9 X 0.50 mm to achieve the industry leading size 1.1 x 0.9 x 0.50 mm footprint. The filter exhibits excellent power handling Product Features capabilities. Low Loss in WLAN band with extended upper corner for inclusion of Bluetooth High Rejection in B30/B38/B7/B41 bands Industry leading small size: 1.1 x 0.9 x 0.5 mm Functional Block Diagram Performance over 40 to +95 C Single Ended operation Gnd RoHS compliant, Pb-free module package Output 5 4 Input 1 Applications 2 3 Gnd WiFi bandpass filter that enables the coexistence of (LTE/TD-LTE) & Wi-Fi Gnd Portable Hotspots Top View Wi-Fi Routers and LTE Gateways Pin Configuration - Single Ended Smart Meters Wi-Fi Access Points Pin No. Label Small Cells 1 Input 4 Output 2,3,5 Function label Note: 1.

All specifications are based on the Qorvo schematic shown on page 5. 2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over temperature. 3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances. 4. An external impedance matching network with 2% tolerance will be necessary to achieve the stated specifications. 5. Typical values are based on average measurements at room temperature. 6. Data is the integrated value of the linear s-parameter over a 19 MHz range in the indicated band at the specified temperature. 7. Data is the integrated value of the linear s-parameter over 5MHz range at the specified temperature. 8. Input power applied for a minimum of 5,000 hrs. at 55C in the frequency band specified. 9. This is the optimum impedance in order to achieve the performance shown. Advanced Data Sheet: REV F October 2018 - 2 of 8 - www.qorvo.com Subject to change without notice
