Keysight has introduced a new solution for 6G Sub-THz active device characterization in linear and nonlinear regions using a PNA-X network analyzer, Arbitrary Waveform Generator, and VDI (Virginia Diodes Inc.)’s millimeter-wave frequency extenders. The Keysight 6G Vector Component Analyzer (VCA), based on the new N524XB series PNA-X Microwave Network Analyzers, offers a modulation bandwidth of 4/10/40 GHz which makes it the ideal choice to develop and characterize components for sub-THz communication systems for emerging 6G applications.
Characterizing components at sub-THz frequencies without introducing error
Characterizing sub-THz components for 6G requires more than S-parameters to be comprehensive. Noise figure, gain compression, and error vector magnitude as well as a number of other modulated measurements are needed to create a complete picture to predict component performance in a system. Time-domain and frequency-domain measurements are essential to accurately characterize components at these sub-THz frequencies.
The setup for 6G sub-THz component characterization requires a modulated wideband signal source and a vector network analyzer that can both take S-parameter measurements and traditional modulated measurements. These systems must be fully clock-locked in order to reduce the phase noise at sub-THz frequencies. Finally, given the effects the test system and any fixtures can have on these sub-THz signals, source calibration is critical to ensure an ideal test signal at the device under test (DUT) input reference plane.
6G component characterization solution
Characterizing sub-THz components requires instrumentation that can accurately make S-parameter and modulated measurements at new 6G frequencies without introducing error. The Keysight 6G Vector Component Analysis Solution comprises a 4-port PNA-X network analyzer, test set controller, arbitrary waveform generator, and external up and downconverters. Working together, these products streamline sub-THz component characterization and predict system performance with time and frequency domain measurements from a single test system.
