QPQ5501 Band Boost Filters

The Qorvo QPQ5501 is a high-performance, high-power bulk acoustic wave (BAW) band-pass filter that features exceptionally steep roll-off characteristics. It delivers low-insertion loss within the Wi-Fi UNII 2c-4 bands while providing strong near-in rejection across the UNII 1-3 bands and UNII 5-8 bands. This filter module is purpose-built to support industry-leading capacity in Wi-Fi systems, enabling higher power operation across more channels compared to systems using no filtering or traditional filter solutions. As a result, end users benefit from improved performance in applications that utilize sub-banding across the 5 GHz and 6 GHz Wi-Fi spectrum, such as tri-radio Wi-Fi mesh networks. The module also leverages standard packaging techniques to maintain a familiar footprint, while minimizing the need for external passive components and streamlining integration into customer designs.
