    The QPQ1902 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 rejection in the band-edge and adjacent LTE /TD-LTE bands.

    The QPQ1902 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 implementation into high performance high power access points and small cell base stations.

    The QPQ1902 uses common module packaging techniques to achieve the industry standard 1.4 x 1.2 x 0.50 mm footprint.
