What Milliwave Silicon Solutions does
Milliwave Silicon Solutions Inc., operating under the brand MilliBox, designs and manufactures modular, benchtop over-the-air (OTA) antenna test systems for mmWave and sub-THz frequency applications. The company's core product portfolio consists of two complementary product lines: (1) modular anechoic chambers in 24-inch (MBX0x) and 30-inch (MBX3x) cube configurations with corrugated absorbers providing approximately 50dB mmWave attenuation, and (2) a family of 3D antenna positioners (GIM series, including the GIM04 HV, GIM05 spherical roll, and GIM06 variants) with sub-0.1 degree resolution. A defining technical feature is the use of non-metal frame construction (less than 1% metal, using wood, PVC, PLA, and nylon) to minimize stray mmWave reflections, with instrument bays positioned below the chamber deck to keep cable runs short. The company also offers application-specific configurations including the MBX32CTR Compact Antenna Test Range (CATR), MBX33R mmWave radar test system, and MBX32E sub-THz OTA system, plus accessories such as the Fast Synchronized Trigger (FST) feature, frequency extender kits (EXTxx), cable assemblies, and radar target mounts.
The MilliBox product line was invented and launched in 2018 by founders Chinh H. Doan and Jeanmarc Laurent, both mmWave IC industry veterans, after the company was established in 2016 in San Jose, California. As of November 2022, over 250 systems had been installed worldwide across startups, multinational corporations, universities, and the defense sector. The customer base spans automotive mmWave radar development, 5G NR and 6G/sub-THz communications research, defense and SATCOM, meta-surface research, consumer sensors, and academic education. Named users and partners include Anokiwave, pSemi/Murata, Copper Mountain Technologies, and the Centre for Intelligent Antenna and Radio Systems (CIARS) at the University of Waterloo.
The business model is hardware-centric: MilliBox sells chambers, positioners, and accessories primarily as quote-based direct sales, supplemented by a 'Build Your MilliBox' web-based configuration tool and a network of regional representatives and distributors covering the Eastern US, DACH region, UK/Ireland, France/Belgium, Japan, China, and South Korea. The Python-based software controller is provided in open-source form. No public pricing is disclosed, and no funding rounds have been reported; the company operates as a privately held, founder-owned entity with manufacturing performed locally in California.

Milliwave Silicon Solutions competitors and assessment
Company assessmentDirect peers
- ETS-Lindgren: ETS-Lindgren is a leading manufacturer of anechoic chambers and RF test solutions for EMC and antenna measurement. It directly competes with MilliBox in the anechoic chamber segment, though it traditionally focuses on larger walk-in chambers rather than benchtop modular systems.
- Microwave Vision Group (MVG): MVG (formerly Satimo/Orbit) provides antenna measurement systems including multi-probe anechoic chambers and positioners for OTA testing. It serves similar customers (5G, automotive radar, defense) with higher-end systems than MilliBox, making it a direct competitor in the OTA antenna test market.
- NSI-MI Technologies: NSI-MI specializes in antenna pattern measurement systems including spherical near-field, far-field, and compact range systems with positioners. It directly competes with MilliBox for antenna radiation pattern measurement customers in research and commercial labs.
- Bluetest: Bluetest manufactures reverberation chamber (RTS) systems for OTA testing of wireless devices, particularly mobile handsets and small antennas. It overlaps with MilliBox in OTA antenna testing but uses a fundamentally different chamber technology and tends to focus on device-level rather than antenna pattern measurements.
Broad incumbents
- Keysight Technologies: Keysight is the dominant test and measurement incumbent for RF/microwave, with VNAs, signal analyzers, and OTA solutions. It partners with MilliBox for chamber-positioner integrations but also competes as a full-system supplier at the high end.
- Rohde & Schwarz: Rohde & Schwarz provides VNAs, OTA test solutions, and antenna measurement equipment across automotive, wireless, and aerospace markets. It is explicitly listed as a MilliBox VNA integration partner and is also a broader competitor in RF T&M.
- Anritsu:
