OML

OML (Oleson Microwave Labs) is a US-based manufacturer specializing in millimeter wave and sub-millimeter wave measurement components and frequency extension modules. The company produces waveguide-based frequency extender modules that expand the measurement capability of vector network analyzers (VNAs) well beyond their native frequency range, enabling precision S-parameter characterization of components and circuits operating in the mm-wave and THz frequency bands. OML products are engineered for high accuracy and are compatible with VNA platforms from major manufacturers including Keysight, Rohde & Schwarz, and Anritsu.

The frequency extension modules cover bands from W-band (75–110 GHz) through THz frequencies, using waveguide interfaces to provide calibrated, traceable measurements. OML modules are used in research and production environments where standard coaxial-based VNA measurements are insufficient for the frequencies under test.

Key Product Lines

• VNA frequency extender modules — waveguide-based mm-wave modules that extend VNA measurement range into W-band, D-band, and beyond
• Millimeter wave components — waveguide adapters, converters, and passive components for mm-wave test system integration

Industries Served

OML equipment is used in aerospace and defense for radar and satellite payload component characterization, in semiconductor and materials research for on-wafer mm-wave device measurement, and in telecommunications R&D for 5G and beyond-5G component testing at millimeter wave frequencies. Academic institutions and national metrology laboratories also use OML extenders for fundamental mm-wave research and standards development.
