SensorView, founded in 2015 and listed on KOSDAQ in July 2023, is a radio-frequency (RF) connectivity solutions specialist that develops and manufactures ultra-high-frequency cables, connectors, antennas and semiconductor test interfaces in the microwave and millimeter-wave (mmWave) bands.
Its main products include mmWave cables and connectors for test and measurement equipment, mmWave antennas for 5G infrastructure, and compact transmission lines for 5G devices and small cells.
Its customers include Samsung Electro-Mechanics, Samsung Electronics, Qualcomm, SpaceX, Hanwha Systems and Korea Aerospace Industries (KAI).
In defense, the company supplies antennas, adapters and connectors used in multifunction radar, fighter jets and naval electronics through partners such as LIG Nex1, Hanwha Solutions and KAI.
Overseas, it counts defense contractors such as Lockheed Martin, L3Harris and Hyundai Rotem, as well as Nvidia, Broadcom, Qualcomm and Samsung Electronics, among its clients. As of Q2 2025, revenue by segment was roughly 86% civilian, 13% defense and 1% semiconductor, but the defense share expanded to 66% in H1 2026.
New growth areas include antenna subsystems for 6G communication satellites (aerospace), AEC cables for AI data centers, and cryogenic cables and integrated modules for quantum computing. Cryogenic cables have already begun shipping to a domestic government research institute.
