Rohde & Schwarz's millimeter wave converters target W band measurements

Among the important applications that operate in the W band are vehicle distance radar (77 GHz) and aerospace and defense applications (94 GHz). Additional hardware is not necessary, which saves time and costs.

Rohde & Schwarz claims to be the first to support multiport measurements in the W band. The four-port models of the network analyzers do not require an additional external generator, which considerably reduces measurement times.

The R&S ZVA-Z110 converters set standards in the field of test and measurement for the W band. The converters can be integrated into wafer probers. The dynamic range of typ. > 110 dB allows faster measurements and tests on high-rejection filters.

The converters' multiport technology make it is possible to perform three-port and four-port measurements on balanced circuits for MMICs in the automotive area (77 GHz).

Tests on low-noise amplifiers can now be performed more efficiently. These tests require low input power levels, which were not provided in existing solutions. The R&S ZVA-Z110 can continuously attenuate the output power by as much as 25 dB. This is an advantage when doing research on radar and satellite applications.

With respect to test setup, the R&S ZVA-Z110 converters are designed to save time. They are entirely integrated into the firmware of the high-end network analyzers from Rohde & Schwarz and can be operated as if they are part of the base unit.

Diagrams show the user how to connect the converters. The automatic setting of the power levels prevents damage to the converters. Moreover, Rohde & Schwarz offers the R&S ZV-WR10 calibration kit for the W band.

The R&S ZVA-Z110 mm-wave converters for the R&S ZVA24, R&S ZVA40, and R&S ZVT20 network analyzers are now available from Rohde & Schwarz.
