Qorvo QPQ5510 5GHz Wi-Fi U-NII 1-3 bandBoost™ Filter

Introduction

The Qorvo QPQ5510 is a compact RF band-pass filter designed for 5GHz Wi-Fi systems. Using Bulk Acoustic Wave (BAW) technology, it supports the Wi-Fi U-NII 1 through U-NII 3 frequency ranges while helping designers reduce unwanted signal interference in space-constrained wireless products.

Part Description

The QPQ5510 is a high-performance RF band-pass filter covering frequencies from 5170MHz to 5835MHz. It is intended to pass desired 5GHz Wi-Fi signals with low insertion loss while rejecting signals outside the target band, including higher Wi-Fi U-NII 5 through U-NII 9 bands.

Qorvo integrates impedance matching into the filter, reducing the number of external matching components that may be needed in an RF signal path. The device supports average input power levels up to +28dBm, making it suitable for relatively high-power Wi-Fi transmission paths.

Its small 1.8mm × 1.6mm package is useful for compact radio modules, access points, gateways, and portable wireless equipment where PCB area is limited.

Applications

Potential applications for the QPQ5510 include:

• 5GHz Wi-Fi access points
• Wireless routers and mesh-network nodes
• Wi-Fi client devices
• Enterprise wireless infrastructure
• Wi-Fi repeaters and range extenders
• Residential gateways
• Industrial wireless communication systems
• Internet of Things gateways
• Wireless video transmission equipment
• 5GHz radio front-end modules

Industries

Industries that may use this RF filter include:

• Telecommunications
• Consumer electronics
• Networking equipment
• Industrial automation
• Smart home technology
• Healthcare electronics
• Security and surveillance
• Automotive connectivity
• Internet of Things
• Commercial building infrastructure

Usage Ideas

1. Compact Wi-Fi Router Front End
   Place the QPQ5510 in the transmit or receive RF path of a 5GHz router to pass the intended U-NII 1-3 signals while reducing out-of-band interference.

2. Industrial Wireless Gateway
   Use the filter in a robust 5GHz gateway for factory sensors, controllers, or machine-monitoring devices operating in electrically noisy environments.

3. Mesh Wi-Fi Node
   Integrate the QPQ5510 into a mesh networking node to improve RF selectivity for 5GHz backhaul or client connectivity channels.

Conclusion

The Qorvo QPQ5510 is a miniature BAW RF band-pass filter for 5GHz Wi-Fi designs operating between 5170MHz and 5835MHz. With low insertion loss, strong out-of-band rejection, integrated matching, and +28dBm average input-power handling, it is well suited to compact and performance-focused Wi-Fi front-end architectures.
