VNA Frequency Extenders and Calibration Kit
16 September 2025 - Keysight Technologies introduces two new millimeter-wave frequency extender modules, the NA5305A Frequency Extender up to 170 GHz and NA5307A Frequency Extender up to 250 GHz, and the 85065A Precision Calibration Kit 0.5 mm. When used with Keysight’s PNA/PNA-X Vector Network Analyzers (VNA) and the N5292A Test Set Controller, the new accessories enable engineers to achieve fully calibrated single-sweep broadband S-parameter measurements from 100kHz (or 10 MHz) to 170/250 GHz. Existing customers using the 110 GHz /120 GHz VNA can easily upgrade their configuration, providing added value to their original investment.
The 85065A Precision Calibration Kit 0.5 mm enables precise measurements up to 250 GHz when used with the broadband VNA solution. The broadband VNA accessories simplify test setups and allow engineers to characterize various sub-THz on-wafer or packaged components such as optical RF drivers, TIAs, PCBs, cables, packages, and passive devices. The new accessories help engineers characterize these components and reduce lengthy design and verification cycles.
As AI pushes the limits of data communications with 1.6 Tb/s and 3.2 Tb/s networks and wireless research continues in sub-THz frequencies, test and measurement solutions must evolve to keep pace. Engineers developing next-generation semiconductors and high-speed interconnects, millimeter-wave and sub-THz wireless devices, and advanced semiconductors require instruments that deliver accurate broadband VNA measurements at ever-higher frequencies to validate designs and correlate simulations with real-world performance.
Measuring sub-THz signals in on-wafer and packaged components demands specialized probes, adapters, and test cables that complement Keysight’s new frequency extenders and calibration kit to form a comprehensive test setup.
To deliver complete measurement capabilities, Keysight has collaborated with top-tier industry solution partners; FormFactor Inc. and MPI Corp. have engineered advanced single-ended and differential RF probes. In addition, Spinner GmbH, a leading supplier of coaxial adapters, has developed ruggedized 0.5- to 0.8-mm coaxial adapters that support frequencies up to 167 GHz, along with 0.5-mm PC board-mount connectors. Junkosha Inc. has introduced high-performance 0.5-mm test cables.
