    Qorvo's advanced LowDrift™ filters provide industry-leading, ultra-stable temperature performance and an enhanced user experience by enabling the highest level of LTE coexistence wireless network coverage.

    Qorvo's 885070-A is a high-performance, high power Bulk Acoustic Wave (BAW) band-pass filter with extremely steep skirts, simultaneously exhibiting low loss in the Wi-Fi band and high rejection in the band-edge frequencies and adjacent LTE / TD-LTE bands.

    The 885070-A also enables coexistence of Wi-Fi and LTE signals within the same device or in close proximity to one another. Its unique power handling capability allows for implementation into high performance high power access points and small cell base stations. The filter has met stringent automotive requirements derived from the AEC-Q200 standard and is suitable for use in infotainment and telematics applications.

    The 885070-A uses common module packaging techniques to achieve the industry standard 1.7 x 1.32 x 0.46 mm footprint.
