Qorvo® of Greensboro, North Carolina USA, has introduced what it says is the smallest available Bulk Acoustic Wave (BAW) filter that can handle 5W of RF average input power, with peaks up to 40W. Qorvo says that the new BAW filter solves issues of reliability, assembly, as well as testing and space constraint challenges related to designing massive Multiple Input/Multiple Output (MIMO) telecom infrastructure for 5G migration.
To boost LTE Networks now and prepare for 5G performance in heavy traffic areas, Telecom providers are implementing massive MIMO equipment. The use of massive MIMO equipment adds to capacity, enhances signal quality, and improves usage of the existing network spectrum. The QPQ1300 leverages the company’s robust, solidly mounted resonator (SMR) BAW technology, which supports the reliable thermal power dissipation needed for massive MIMO infrastructure equipment.
BAW Filter Saves Space Compared to Ceramic Filter
Measuring just 5mm by 5 mm by1mm, Qorvo says that the new BAW filter represents a 90 percent space savings compared to ceramic filters. The company optimized the QPQ1300 for 2575-2635 MHz, a sub-band for Band 41. Prototype samples of the QPQ1300 are now available for qualified customers.
James Klein, president, Qorvo Infrastructure and Defense Products, said, “The size and power handling capabilities of the QPQ1300 differentiate it from every other filter on the market today. Smaller filters enable telecom equipment manufacturers to design printed circuit boards for space-constrained applications such as massive MIMO in order to improve network capacity using existing LTE network infrastructure.”
Qorvo says that the QPQ1300 expands its line of BAW filters for base stations, which solve complex interference and coexistence challenges. The company also says that its BAW filters enable operators and manufacturers to more efficiently use the existing spectrum for higher speeds and greater bandwidth.
