Electronics Power Supply / Management band-pass BAW filter wirelessQORVO QPQ1903 5 GHz UNII1-2a Bulk Acoustic Wave (BAW) band-pass filter boosts performance and power. Device comes with very steep skirts, while simultaneously exhibiting low loss in the Wi-Fi UNII1-2a band and high near-in rejection in the UNII2c-3 band. Module is specifically designed to enable industry leading capacity performance in Wi-Fi applications that result in higher power capability in more Wi-Fi channels than systems with no or traditional filter solutions. End-users will see a better capability to deliver features that take advantage of sub-banding the 5GHz Wi-Fi spectrum in use cases such as tri-radio Wi-Fi mesh applications. Device uses common module packaging techniques to achieve the industry standard footprint while negating as many external passive placements to help end users ease of integration into their circuits.
