885136
®
2437 MHz BAW Filter
General Description
The 885136 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 885136 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 885136 uses common module packaging techniques
to achieve the industry standard 1.1 x 0.9 x 0.50 mm
footprint.
1.1 X 0.9 X 0.50 mm
