What AmTechs does

AmTechs (株式会社アムテックス) is a privately held Japanese specialized technology distributor headquartered in Setagaya, Tokyo. The company imports and resells RF, microwave, millimeter-wave, submillimeter-wave, THz (terahertz), and GNSS (GPS) sensors, components, and test instruments sourced from over 35 international manufacturers to Japanese engineering companies, research institutions, universities, and government laboratories. AmTechs operates as a B2B direct-sales distributor, not a product developer; its functional role is providing Japanese customers access to otherwise difficult-to-source precision high-frequency and positioning components, combined with technical consultation for product selection and integration.

The product portfolio spans three categories. First, RF/Microwave/THz products including antennas, amplifiers, converters, attenuators, switches, and test instruments from manufacturers such as ERAVANT (formerly Sage Millimeter), Virginia Diodes (VDI), Micro Harmonics, ANTERAL, Marki Microwave, Schwarzbeck, SWISSto12, and Pico Technology. Second, GPS/GNSS products including receivers, antennas, simulators, compass modules, and inertial sensors from NovAtel (Hexagon), Hemisphere GNSS, Calian GNSS (formerly Tallysman Wireless), Spirent Communications (now Keysight), and Movella Technologies (Xsens). Third, a "Unique Products" category extending into LiDAR (OUSTER), FMCW radar (Aeva), and specialty sensors. Notable technical offerings include VDI compact up/down converters for E/W/V-band wireless research, Spirent GSS7000 and PNT-Xe GNSS simulators, NovAtel PwrPak7 OEM7700-based receivers with 16GB onboard memory, and InfiniDome GPSdome anti-jamming devices using null-steering algorithms.

AmTechs' revenue model is hardware resale with a value-added technical-support layer; pricing is quote-based and not publicly disclosed. The go-to-market is sales-led and direct: customers reach the company through industry exhibitions (MWE/Microwave Exhibition, GNSS Symposium, SPEXA, DSEI Japan, AUTOMOTIVE WORLD), a comprehensive corporate-website catalog organized by manufacturer and application, and direct telephone/email inquiry during weekday business hours (9:00-17:00 JST, phone 03-5450-5311). The company is privately held with no disclosed funding rounds, parent company, subsidiaries, or institutional investors, and operates from a single Tokyo office. A new president was appointed in February 2025.
