Keysight unveils millimeter-wave frequency extenders for sub-THz testing

SANTA ROSA, Calif. - Keysight Technologies, Inc. (NYSE:KEYS), a $28.9 billion test and measurement leader with a "GOOD" financial health rating according to InvestingPro, has introduced new millimeter-wave frequency extender modules and a precision calibration kit designed to support testing of next-generation high-speed components operating at sub-terahertz frequencies.

The new products include the NA5305A Frequency Extender (up to 170 GHz), the 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 and the N5292A Test Set Controller, these accessories enable single-sweep broadband S-parameter measurements from 100kHz to 250 GHz. The company’s strong gross profit margin of 62.4% and robust current ratio of 3.59 reflect its ability to invest in innovative solutions while maintaining operational efficiency.

The broadband VNA accessories are designed to simplify test setups for characterizing various sub-THz components including optical RF drivers, transimpedance amplifiers, printed circuit boards, cables, and passive devices.

According to the company, the system achieves a dynamic range of 105 dB at 170 GHz and provides differential measurement capability for validating high-speed interconnects. The frequency extenders deliver maximum output power of 0 dBm at 170 GHz and -5 dBm at 220 GHz.

To create a comprehensive test ecosystem, Keysight has collaborated with industry partners. FormFactor Inc. and MPI Corp. have developed advanced RF probes, while Spinner GmbH has created ruggedized 0.5- to 0.8-mm coaxial adapters supporting frequencies up to 167 GHz. Junkosha Inc. has introduced high-performance 0.5-mm test cables.

"With the introduction of our 170 and 250 GHz broadband VNA extenders, we are delivering the performance engineers need to validate next-generation semiconductors and high-speed network components," said Joe Rickert, Vice President and General Manager of Keysight’s High-Frequency Measurements Center of Excellence, in the press release.

The new test solutions aim to address measurement challenges in developing components for emerging 1.6 Tb/s and 3.2 Tb/s data communications networks and sub-THz wireless devices.

In other recent news, Keysight Technologies Inc. reported its fiscal third-quarter earnings, surpassing Wall Street expectations. The company achieved an earnings per share (EPS) of $1.72, which was higher than the forecasted $1.67.
