Optimized for high capacity performance in Wi-Fi applications
Compact surface-mount package suitable for space-constrained designs

Applications

5GHz Wi-Fi UNII2c-3 band signal conditioning
Wireless LAN infrastructure equipment
High-density Wi-Fi access points

Procurement Notes

Verify the specific suffix against official Qorvo documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with moisture sensitivity level requirements during storage and assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when designing for the 5.6625GHz center frequency with a 345MHz bandwidth requirement. The 2dB insertion loss specification makes it suitable for applications demanding efficient signal transmission. Consider the 1.70mm x 1.10mm footprint for PCB layout constraints. Verify that the steep skirt performance aligns with adjacent channel interference mitigation needs in dense wireless environments.
