Microwave, millimetre wave and terahertz technology, 6G and IoT, alongside radar technologies, radar signal processing, algorithms and AI, will be the dominant topics at the European Microwave Conference 2025 in Utrecht. From 23-25 September, Aaronia will be presenting its SPECTRAN V6 real-time spectrum analyser solutions and a broadband antenna range at one of the most important trade fairs for microwaves and RF in Europe.
Aaronia will showcase the fast, USB-based SPECTRAN V6 solutions. With a real-time bandwidth of up to 490MHz and a sweep speed of 3THz/s, the SPECTRAN V6 Xplorer is the new reference in terms of speed. Equipped with waveguide connections, the analyser enables measurements in the millimetre wave range that are not possible with conventional cables.
Wave guides transmit the signal without distortion or loss. They are less susceptible to external disturbances such as electromagnetic interference, which is important in an environment with many electrical devices and radio signals. As a result, the signal remains clean and the spectrum analyser’s measurements are not distorted. The SPECTRAN V6 Xplorer sets a new benchmark with measurements up to 140GHz and still offers the benefits of low-cost USB devices.
However, speed and precise measurements are not only required in the microwave range, but also in the new WLAN structures. For instance, the introduction of 320MHz channels in the WLAN standard IEEE 802.11be (Wi-Fi 7) poses new challenges for measurement technology. The entire channel width with short-term interference, transients or burst signals within the 320MHz spectrum must be recorded simultaneously and in real time. Added to this are the dynamics of the spectrum in the high-frequency range. Modern WLAN signals work with extremely short packet propagation times and adaptive modulations. Fast FFT processing is important here, as is the largest possible working memory for trigger data and ideally also the reconstruction of signals time-correlated with I/Q data.
The situation is similar in the mobile communications sector with 5G and 6G. In each case, a wide range of frequency bands are used that have significantly higher frequencies than previous mobile communications standards. One example of this is the extremely high frequency (EHF) band from 30GHz to 300GHz.
The analysis of such high-frequency signals calls for spectrum analysers that offer high frequency resolution and sufficient bandwidth to represent the complex structure of the signals. Additionally, 5G systems use beamforming techniques and massive MIMO (multiple input multiple output), which further complicates the analysis. Aaronia supplies equipment variants with the SPECTRAN V6 5G for this purpose and for measurements in the mobile radio environment. The device also supports the WiGig 45 GHz (802.11aj) and 60 GHz (802.11ad/aj/ay) profiles, which are now included in the latest version of the RTSA Suite PRO for signal recording and data analysis.
In order to fully exploit the performance of the SPECTRAN V6 real-time spectrum analysers, Aaronia, from Germany, is also presenting its broadband antenna range. Included here are the brand new PowerLOG horn antennas up to 70GHz as well as the real-time DF solutions based on the improved and further developed IsoLOG DF DF and tracking antenna. Also on display will be the new IsoLOG DF 16-10180 with a frequency range of 1GHz – 18GHz and the IsoLOG DF 16-20400 with a frequency range of 2GHz – 40GHz.
