2.4 GHz WLAN BT / LTE Coexistence Filter

Part # 885128


Key Features

  • Wi-Fi bandpass filter that enables the coexistence of 4G LTE / TD-LTE & Wi-Fi signals
  • High rejection in adjacent LTE bands B7 / B41 / B38 / B40
  • Industry leading small size: 1.1 x 0. 9 x 0.5 mm
  • Extended temperature performance over -40 to +95 C
  • Meets +38dBm peak power handling
  • RoHS compliant, Pb-free package
  • Lead-free / RoHS Compliant


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 band-edge & near-in rejection.

The 885128 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 and small cell base stations.

The 885128 uses common module packaging techniques to achieve the industry leading small size 1.1 x 0.9 x 0.5 mm footprint. The filter exhibits excellent power handling capabilities.
