What Silicon Radar does

Silicon Radar GmbH is a Frankfurt, Germany-based designer of high-frequency millimeter wave radar integrated circuits. Founded in 2006, the company developed radar sensor technology operating across 24, 60, 77, 120, and 240 GHz ISM frequency bands, with proprietary capability in FMCW and CW radar operation and a theoretical range resolution of 3.3mm at the 240 GHz band. The company's products are targeted primarily at automotive safety applications including advanced driver-assistance systems (ADAS), collision detection, adaptive cruise control, and electric vehicle integration, with secondary applications in industrial sensing, agricultural monitoring, and smart city infrastructure.

In February 2023, Silicon Radar was acquired by indie Semiconductor (NASDAQ: INDI), a publicly-traded automotive semiconductor company, and was integrated into indie's Radar Sensors & Systems division. The acquisition was structured to accelerate indie Semiconductor's development of high-frequency radar SoCs for autonomous driving and EV safety applications. Silicon Radar's German-based millimeter-wave IC engineering team and its proprietary technology across higher ISM bands (120 GHz and 240 GHz) were cited as the strategic rationale. Following the acquisition, Silicon Radar's commercial operations — including sales, distribution, and marketing — are conducted through indie Semiconductor's global channels.

Prior to the acquisition, Silicon Radar operated as a privately-held fabless semiconductor design house with 11–50 employees and raised approximately $7.3M across disclosed funding rounds in 2015 (bmp Ventures, Horizon 2020) and 2019. No independent revenue, pricing, or customer concentration data is publicly disclosed for the standalone entity.
