Keysight Technologies has launched a broadband millimetre-wave network analyser solution that delivers unparalleled system-level ac­cu­­racy of up to 120 GHz. The new Keysight N5290/91A solutions produce metrology-grade results that enable developers to confidently characterise their millimetre-wave designs. Further, they enhance device characterisation and modelling by delivering exceptional stability and accuracy for on-wafer and connectorised measurements.

The core elements of the system are a Keysight PNA or PNA-X network analyser, along with N5293A Series compact frequency extenders and the N5292A test-set controller. In order to simplify benchtop measurements, engineers can mount the frequency extenders on an optional desktop positioner. The solution’s calibration capabilities are based on an improved-accuracy database that supports a 1 mm calibration kit (85059B) and a 1 mm verification kit (85059V). Further, the magnitude stability of the solution is less than 0.015 dB and the phase accuracy is less than 0.15 degrees over a 24-hour period. The optional 900 Hz start frequency enables engineers to characterise the low-frequency performance of their devices. This is especially useful when measuring the low-loss transmission line structures that are commonly used in highspeed digital applications.

In addition, the broadband millimetre-wave solution supports a variety of Keysight’s proven measurement applications. This includes the complete characterisation of amplifiers and frequency converters (gain compression software option), measurement of mixers and frequency converters (scalar mixer software option), and calibrated multichannel spectrum measurements (extended spectrum analyser software option).
