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
to achieve the industry leading size 1.1 x 0.9 x 0.50 mm
footprint. The filter exhibits excellent power handling
capabilities.
1.1 X 0.9 X 0.50 mm

Notes:
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 55 °C in the frequency band specified.
9. This is the optimum impedance in order to achieve the performance shown.
