Mauna Kea Semiconductors Corporation
Mauna Kea Semiconductors (MKSemi) is a Silicon Valley fabless chip company building what it calls the world's lowest-power ultra-wideband (UWB) technology - the short-range radio that lets phones, wearables, cars and IoT devices know precisely where they are and which direction they're pointing, down to a few centimeters. Founded in 2019 by semiconductor veterans and headquartered in Cupertino/San Jose with engineering hubs across China, MKSemi sells UWB chips, modules and SDKs, headlined by its highly integrated MK8000 SoC, to device OEMs and ODMs chasing precise location, secure ranging and radar-style sensing on coin-cell batteries.
SPARK Microsystems
SPARK Microsystems is a Montreal-based fabless semiconductor company building ultra-wideband (UWB) wireless transceivers that aim for wire-like performance without the wire. Its patented LE-UWB technology delivers ultra-low latency, high data throughput, and very low power draw, targeting applications where Bluetooth falls short: wireless audio, gaming peripherals, AR/VR and AI wearables, presence detection, and industrial IoT. Founded in 2016 by researchers out of Montreal's engineering community, SPARK has raised roughly CAD $48M+ and is scaling commercial adoption of its second-generation SR1120 transceiver.
