Munich, Germany — Following the successful launch of converters for the 75 GHz to 110 GHz range, Rohde & Schwarz is now offering converters for the ranges 50 GHz to 75 GHz and 220 GHz to 325 GHz. The converters connect directly to analyzers of the company's ZVA series. No extra hardware is required. With this new equipment, even multiport measurements up to 325 GHz can be implemented for the first time.
Network analysis in the millimeter-wave range has - until now - been restricted to two-port measurements. To carry out complete multiport measurements on devices such as couplers, for example, the ports had to be reconnected because it was not possible to measure all S-parameters simultaneously. The four-port network analyzers of the ZVA family together with the company's converters for the V, W and J bands enable measurements up to 325 GHz for the first time with up to four ports. Results are immediately available, and full multiport system error correction further enhances measurement accuracy.
On top of this, the converters offer maximum performance in terms of dynamic range, which exceeds 90 dB at 75 GHz and 60 dB (typical 80 dB) at 325 GHz. This level of performance even enables high-blocking filters to be analyzed. Output power is adjustable, which facilitates tests on amplifiers in the development stage, for example.
All converters are fully integrated into the network analyzer firmware, which means they can be operated as if they were part of the base unit. Diagrams show the user how to connect the converters. Further, a function that automatically limits output power prevents damage to the converters.
The ZVA-Z325 and ZVA-Z75 millimeter-wave converters and the corresponding ZV-WR03 and ZV-WR15 calibration kits are available now.
