The company’s first millimeter-wave equipment followed in the late 1980s with signal generators that reached above 26.5 GHz (with upconverters) and broadband network analyzers that covered 45 MHz to 100 GHz. Since then, key introductions include 67 GHz network analyzers (PNA, 2006) and 50 GHz handheld spectrum and combination analyzers (FieldFox, 2015).Other examples include: 90 GHz wide-bandwidth oscilloscope (86100D Infiniium DCA-X); 68 GHz wideband transceiver (E7760A); 67 GHz microwave network analyzers, extendable to 1.1 THz (PNA-X); 67 GHz analog signal generator, extendable to 1.1 THz (E8257D PSG); 63 GHz oscilloscopes (Infiniium Z-Series); and 50 GHz PXIe performance vector signal analyzer (M9393A).Keysight launched the N9041B UXA in October 2016.
Through the use of frequency-extender products from two solution partners, Virginia Diode, Inc. (VDI) and OML, Inc., many Keysight signal generators, spectrum analyzers and network analyzers can cover frequencies between 50 GHz and 1.5 THz. As an example, a recently deployed solution includes spectrum analysis capability up to 1.5 THz.
Keysight software products address the need to integrate design, simulation, measurement, and analysis at millimeter-wave frequencies. Software solutions for design and simulation provide an efficient workflow that accelerates development of next-generation devices and systems.
The Keysight EEs of EDA suite includes circuit simulators, electromagnetic solvers and device-modeling solutions that help designers enhance their work from first design through first prototype. In fact, the N9041B R&D team used Keysight Advanced Design System (ADS) software to achieve first-time-correct designs of the millimeter-wave filters used in the front end of the analyzer.
Conclusion
For more than 75 years, engineers have counted on Keysight to give them easier access to accurate, repeatable measurements at ever-higher frequencies and wider bandwidths. Today, the company is extending the leading edge for R&D engineers performing design, simulation and measurement at millimeter-wave frequencies. New products such as the N9041B UXA signal analyzer and an upcoming oscilloscope based on next-generation InP process are testament to Keysight’s ongoing leadership in solutions for millimeter-wave applications.
