S-parameter Measurement System

DPS21 - KEYCOM Corp (KEYCOM)

Unlike a coaxial tube type or a wave guide tube type, this method does not make errors caused by air-gap as specimens are not put into a fixture. Practical data can be obtained even at the rough, uneven surfaces where the specimen is placed on.
It enables compactness and measuring specimens by plane wave because of direct installment of lens with an antenna.
It enables measurement by monitoring S21 and S11 parameter with connections of a test fixture to a vector network analyzer and PC.
