Analog, Power, RF companies
87 companies in the Analog, Power, RF part of the semiconductor & AI value chain — Analog, power, and RF chips interface between the physical and digital worlds — converting signals, managing power delivery, and handling wireless communication. Unlike logic chips, many analog designs remain valuable on older process nodes, giving established players long product cycles. Texas Instruments leads general-purpose analog; Infineon leads power semiconductors (including SiC for EVs); Murata and TDK lead in RF components and passive electronics; Sony leads in CMOS image sensors. The SiC and GaN power segments are growing rapidly with electric-vehicle and AI-server demand.
