Designed for cellular and SCDMA applications, this component operates at a frequency of 881.5MHz with a bandwidth of 25MHz. It features an insertion loss of 1.9dB and is housed in a compact 5-SMD surface mount package measuring 0.055 inches in length by 0.043 inches.

Feature Summary

• Utilizes Surface Acoustic Wave technology for efficient signal filtering
• Optimized for low insertion loss to maintain signal integrity
• Designed for surface mount integration into compact devices

Applications

• Cellular communication systems
• SCDMA network infrastructure
• Mobile device front-end modules

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before procurement. Confirm that the 5-SMD package dimensions align with your PCB footprint requirements. Ensure compatibility with your assembly process parameters. Check for any recent product change notices or end-of-life announcements from the manufacturer.

Selection Notes

Select this component when a dedicated SAW filter is required for the 881.5MHz band within cellular or SCDMA architectures. The low 1.9dB insertion loss makes it suitable for power-sensitive designs. Consider the small 5-SMD form factor for space-constrained mobile applications requiring precise frequency selection.

Part Context

This part belongs to the Qualcomm RF Front-End portfolio, which includes various discrete filters and duplexers. These components leverage advanced acoustic technologies like ultraSAW to address 4G and 5G design challenges. The series supports energy-efficient multimode devices across consumer and industrial IoT sectors.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Do not assume cross-compatibility with other SAW filters without verifying electrical specifications and pin configurations.
