More About pSemi
pSemi Corporation operates as a fabless semiconductor design and engineering company focused on radio frequency (RF), analog, mixed-signal, and power management integrated circuits used in communication, automotive, industrial, and consumer systems. Its portfolio is oriented toward high-frequency and high-integration components that allow equipment vendors and device manufacturers to implement RF front ends, power delivery networks, and precision analog functions within space- and power-constrained designs. pSemi is a subsidiary of Murata Manufacturing, and its products complement Murata’s passive components and modules within larger electronic systems.
Within enterprise and carrier infrastructure, pSemi devices are used in 5G base stations, small cells, and related radio units, where RF switches, low-noise amplifiers, power amplifiers, and tuners (RF components) support multi-band, multi-antenna architectures such as massive Multiple-Input Multiple-Output (MIMO) and beamforming. These components are designed to work with standard RF system architectures and communication protocols used in cellular networks and wireless backhaul. In broadband and wired communications, pSemi provides ICs that support high-speed signal paths and front-end conditioning for network equipment used in data centers, access networks, and customer premises devices.
For automotive and industrial customers, pSemi offers application-targeted ICs for power management, sensing interfaces, and RF connectivity (automotive and industrial semiconductors). These devices are positioned for use in advanced driver-assistance systems (ADAS), connected car platforms, industrial automation, and Internet of Things (IoT) gateways. The company aligns its product development with common automotive and industrial reliability and qualification standards, which enables use in longer-lifecycle platforms and harsher operating environments compared with typical consumer designs.
Technically, pSemi’s solutions leverage RF CMOS and other semiconductor process technologies to integrate multiple RF and analog functions into single chips or compact modules (integrated RF solutions). This integration reduces external component counts and can simplify board design for OEMs. The company’s RF and analog catalogs are organized around functions such as switching, amplification, tuning, filtering control, and power management, rather than end-user devices, which supports reuse across different sectors including smartphones, infrastructure, and industrial systems.
In marketplace and directory taxonomies, pSemi is categorized under RF and analog semiconductor vendors, with product groupings that include RF front-end ICs for wireless and 5G (RF infrastructure components), power management ICs for enterprise, industrial, and automotive electronics (power management semiconductors), and mixed-signal/control ICs that support sensing, actuation, and system control (mixed-signal ICs). Enterprise architects, hardware engineers, and system designers typically evaluate pSemi alongside other RF and power semiconductor providers when selecting components for communication equipment, automotive ECUs, industrial control systems, network devices, and connected IoT hardware.
