The Automatic Radio Frequency Techniques Group (ARFTG) is a technical organization interested in all aspects of RF and microwave test and measurement. ARFTG was created in 1972 to help end-users get the most from the latest generation of test and measurement equipment. In the early years, the primary focus was on instrumentation automation and calibration. In the meantime, measurement techniques have evolved greatly, and now include such diverse topics as nonlinear measurements, production testing, temporal measurements, high frequency fixturing and probing, multi-port network analysis, mixed-signal measurements, mmWave, and THz measurements. The broad range of ARFTG interests is reflected in the nature of the conferences.
Topics: Calibration and characterization, incl. cryogenic, for quantum technology; EM characterization, incl. de-embedding, of materials and biological samples; On-wafer measurements of RF to subTHz devices and circuits; Waveguide and free-space subTHz and THz measurements; Generation and measurement of sub-THz signals with wideband modulation; Nonlinear characterizations, incl. linearization, of devices, circuits, and systems; Over the air (OTA) calibration and measurement for 5G/6G and Internet of Things (IoT) ; Other recent developments in metrology incl. measurement uncertainty;
