基地台 Remote Radio Head (RRH)
包括5G在內的高速通訊基地台需要透過無線電解調和分組處理進行大容量訊號處理,因此需要使用大功率、高速的系統。此外,由於需要根據處理能力和通訊距離設置很多通訊單元,因此還要求體積小且可以安裝在任何地方。除了功率半導體,羅姆還擁有可用於各區塊的小型、高耐壓半導體元件,以及可減少元件個數的高效電源IC產品系列,為您提供不僅有助於降低功耗,還有助於裝置小型化的解決方案。

Topology Selection
When designing an electronic circuit, especially power system circuits, it is necessary to select a circuit configuration (topology) that meets the required specifications because input voltage, output voltage, power, isolation, etc. vary depending on the application. The selection of the most suitable components also differs depending on the topology. If the wrong components are selected, the required specifications cannot be met and the circuit design must be redone. The topology selection page provided by ROHM guides you through the selection of the best device for different topologies.

Flexible lines
ROHM Apollo’s Hirokawa Factory in Fukuoka Prefecture began operating a new semiconductor back-end process line. Sample production for sales expansion started April 2021. The following year, in 2022, we began mass producing discrete products. The clean room, which embodies the concept of an ‘unmanned high-mix production line’ features a compact design using three sets of equipment neatly arranged in a U-shape with AGVs (Automated Guided Vehicles) running between them. Technicians monitor the status of all lines via monitors in an adjacent control room.
