Keysight Technologies, announced the launch of two new millimeter-wave frequency extender modules – the NA5305A Frequency Extender up to 170 GHz and the NA5307A Frequency Extender up to 250 GHz – along with the 85065A Precision Calibration Kit 0.5 mm. These innovations expand Keysight’s broadband vector network analyzer (VNA) solutions, enabling engineers to perform fully calibrated single-sweep broadband S-parameter measurements from 100 kHz (or 10 MHz) to 170/250 GHz when paired with Keysight’s PNA/PNA-X VNAs and the N5292A Test Set Controller.
The new accessories provide a clear upgrade path for customers currently using Keysight’s 110 GHz or 120 GHz VNAs, delivering extended performance while maximizing their original investment.
The 85065A Precision Calibration Kit 0.5 mm ensures precise measurement accuracy up to 250 GHz, simplifying test setups for broadband characterization of sub-THz on-wafer and packaged components, including optical RF drivers, TIAs, PCBs, cables, packages, and passive devices. By reducing setup complexity and measurement cycles, engineers can accelerate design validation and shorten time-to-market.
As AI adoption drives demand for 1.6 Tb/s and 3.2 Tb/s data networks and wireless research advances into sub-THz frequencies, test and measurement systems must scale to meet the challenge. Keysight’s latest broadband VNA accessories address these needs, equipping engineers with the precision required to validate next-generation semiconductors, high-speed interconnects, and advanced wireless devices.
