Rohde & Schwarz rolls out millimeter-wave converters
The millimeter-wave converters analyze the power-dependent behavior of amplifiers and mixers.

To simplify amplifier measurements in the E and W bands, Rohde & Schwarz has introduced two millimeter-wave converters that feature electronically adjustable output power. The company claims that its ZVA-Z90E, for the E band, and ZVA-Z110E, for the W band, let you analyze the power-dependent behavior of amplifiers and mixers quickly and easily.
With frequency ranges of 60 GHz to 90 GHz and 75 GHz to 110 GHz, the millimeter-wave converters can be applied in high-frequency research, as well as automotive, aerospace, and defense industries. Both models have a dynamic range of typically greater than 110 dB. Output levels can be adjusted electronically in connection with a power calibration for greater accuracy. What's more, the ZVA-Z90E and ZVA-Z110E allow true differential four-port measurements up to 110 GHz.
Like Rohde & Schwarz' other millimeter-wave converters, the two new models can be operated using one of the high-end vector network analyzers in the company's ZVA or ZVT families. The converters are fully integrated into the firmware of the vector network analyzers and can be operated as if they were part of the base unit.
