Base Station Remote Radio Head (RRH)
5G and other high-speed communication base stations require fast, high power systems to perform large-capacity signal processing for wireless demodulation and packet processing. At the same time, since many communication cells are used based on processing capacity and communication distance, they must be small enough to be installed virtually anywhere. In addition to power semiconductors, ROHM offers a lineup of compact, high voltage devices suitable for each block together with high efficiency power supply ICs that can reduce the number of components, providing solutions that contribute not only to lower power consumption, but greater miniaturization as well.

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.
We provide solution boards that solve various customer problems by combining ROHM ICs and discrete products. System-level evaluation results and design data as reference designs are also offered to help customers reduce development load.
Various simulation models for circuit and thermal simulations of power devices and ICs can be downloaded from individual product pages or the following links.
Common to All Products
(op amps, power management ICs, power supply ICs, etc.)
・ Unencrypted SPICE (downloadable from each product page)
This is an unencrypted version of PSPICE, a SPICE model that can be imported into any simulator.
ROHM Solution Simulator is a new web-based electronic circuit simulation tool that allows a variety of simulations to be carried out, from initial development that includes component selection and individual device verification to the system-level verification stage. This makes it possible to quickly and easily implement batch verification of ROHM power devices (i.e. SiC) and ICs (e.g. driver and power supply ICs), in simulation circuits under close to actual conditions, significantly reducing application development load.

ROHM SiC Power Solutions
ROHM offers SiC power devices and solutions that contribute to greater application miniaturization and efficiency. Please consider ROHM for all your SiC design needs.
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.
