Skyworks Solutions is an active US RF semiconductor maker (RF front-end modules, power amplifiers, filters) — but it holds no IEEE OUI block. No maclookup.app vendor page or IEEE OUI was found for "Skyworks Solutions" or "Skyworks Solutions, Inc." across multiple searches. The reason is structural: Skyworks makes fabless RF front-end components that sit inside phones and IoT devices but are not the networked interface, so they don't carry the device MAC, and there is no "Skyworks" OUI even though Skyworks chips are in countless iPhones. One forward-looking corporate note: Skyworks and Qorvo announced a definitive merger agreement on 2025-10-28 valuing the combined enterprise at about $22 billion (Qorvo holders to receive $32.50 cash plus 0.960 Skyworks share each; Skyworks holders to own ~63%), expected to close in early calendar year 2027 — this is not yet closed and is flagged as forward-looking. This entry is included deliberately so the reference documents the absence. For triage, do not expect to identify Skyworks silicon via OUI — there is none; a device using Skyworks RF surfaces under the host brand's or the Wi-Fi/BT chipset/module vendor's OUI instead.

- Company status
- active US RF semiconductor maker; Skyworks + Qorvo definitive merger announced 2025-10-28 (~$22B combined EV; Skyworks holders ~63%), expected to close early calendar 2027 — forward-looking, NOT closed [Unverified — pending close] — en.wikipedia.org
- Device types
- RF front-end modules, power amplifiers, filters — components inside phones/IoT; do NOT carry the device MAC [Confirmed] — skyworksinc.com
- Notable products
- RF front-end modules and power amplifiers (in many iPhones and other handsets)
- Verified prefix
- none (no registered OUI) [Confirmed]
- Special note
- Negative finding included deliberately. Even though Skyworks chips are in countless iPhones, there is no "Skyworks" OUI because RF front-end parts aren't the networked interface. The Skyworks+Qorvo merger (announced 2025-10-28, expected early-2027 close) would consolidate Qorvo's existing OUI footprint under a Skyworks-controlled entity. The IEEE registry publishes no assignment dates, and Skyworks has no block. [Confirmed]
