The B39192-B3824-U810 is a Surface Acoustic Wave (SAW) filter manufactured by Qualcomm Technologies, designed for RF front-end applications. It operates at a center frequency of 1.91 GHz with a bandwidth of 20 MHz. The component is housed in a compact package measuring 0.043 inches (1.10 mm) in maximum height. It is specifically engineered for cellular and CDMA network environments to provide essential signal filtering.
Verify the current lifecycle status before procurement, as documentation indicates this product series may be withdrawn or subject to phase-out notices. Confirm compatibility with existing design specifications and ensure that alternative sourcing options are available if standard supply channels are restricted due to end-of-life procedures.
Select this component for designs requiring SAW-based filtering at 1.91 GHz within cellular/CDMA bands. Evaluate mechanical constraints against the 1.10 mm maximum height profile. Ensure the application environment supports the specific acoustic properties of SAW filters compared to BAW alternatives for the target frequency range.
This part belongs to the Qualcomm B39192 series of RF front-end filters. These components are part of a broader portfolio aimed at supporting wireless connectivity solutions. The specific model targets niche requirements within legacy and specialized cellular networks, distinct from modern 5G ultraBAW offerings.
Check official Qualcomm notifications for designated replacement part numbers associated with the B3824 series withdrawal. Verify electrical equivalence and pinout compatibility before substituting with newer generation RFFE filters.
