Rohde & Schwarz/Kyocera

Visitors at the Kyocera booth saw the R&S ATS1800M 5G NR multi-directional mmWave test chamber from Rohde & Schwarz, designed for over-the-air (OTA) testing with an exceptionally small footprint. The demonstration focused on mobile communications in the 5G FR2, n257 band. Mobile communications in this frequency range experience a high path loss, which can be solved using beamforming antenna arrays. In contrast to traditional antennas, FR2 antennas typically use phased arrays with a high number of individual antenna elements. Kyocera has developed a novel phased array antenna module (PAAM) featuring 384 dual polarization elements, which can create up to eight simultaneous beams in different directions at different frequencies. With this design, the PAAM can be used in site installations, allowing multiple operators to run networks on different frequency bands. In protection applications, PAAM technology can be adapted to sense threats, perform surveillance and communicate simultaneously. However, all of these antenna elements must work together perfectly to form an RF beam with the desired characteristics. Rohde & Schwarz offers a patented approach for OTA testing of such a complex antenna array in a fully shielded environment, which helps engineers verify the correct beam pattern and supports the process of minimizing sidelobes.  

Rohde & Schwarz

Rohde & Schwarz introduced the new FSWX signal and spectrum analyzer with its new architecture, meticulously engineered to overcome these challenges with a strong focus on wideband signal analysis. The FSWX’s key features and innovations include:

• Multiple Input Ports: The FSWX’s ability to connect multiple signal sources simultaneously, regardless of whether they operate at the same or different frequencies, enables many new measurement scenarios. With two synchronous input ports, each boasting a 4 GHz analysis bandwidth, users can seamlessly analyze the interactions between diverse signals.
• Cross-correlation: Cross-correlation mode is a new built-in feature of the FSWX. A single signal input is internally split into two independent signal paths, each equipped with its own local oscillator and analog-to-digital converter (ADC). This design allows for the application of advanced cross-correlation algorithms in the digital backend, effectively filtering out the inherent noise of the measurement instrument and increasing measurement clarity.
• Advanced Filter Banks: The FSWX features comprehensive filter banks that span the entire operating frequency range, diverging from traditional spectrum analyzers that rely on YIG filters. YIG filters are known for having challenging frequency responses and introducing inaccuracies in wideband signal analysis. The filter banks of the FSWX complement YIGs to provide high precision and reliability, optimizing instrument settings for specific applications and reducing the risk of unwanted signal images contaminating results.

Here is a link to the product feature article covering more details.
