MUNICH -- Karl Suss, a unit of Suss MicroTec AG, has introduced a new probe head for testing advanced communications devices with measurements up to 110 GHz. The PH300HF has been designed for stable measurements in the very high frequency (VHF) range without phase errors, said the company.
"Although most components that are being tested right now are in the 20- to 40-GHz range, the market is seeing a rise in demand for higher frequencies in the research and development fields," said Claus Dietrich, international product manager for probe systems at Karl Suss. "This is due to the emergence of such technologies as distance sensors for cars which work in the 80-GHz range."
To address high frequency applications, Karl Suss said it has mounted the probe tip and tuner directly on the PH300HF to ease measurement problems in the VHF range. At these very high frequencies, measurements are highly sensitive and any movement results in incorrect measurements, said the company. Heavy tuners are often places away from the prober with long connecting cables to dampen the signals. Cables can also be bent when moved, causing additional errors in measurements, Karl Suss noted.
The new probe head system allows measurements up to 110 GHz when the prober is used with industry standard network analyzers, according to the Munich company.
