Multi-tone testing has many benefits. While the multi-tone method was initially implemented to increase the speed of IEC 61000-4-3 radiated immunity testing, it has been found that this method also improves equipment efficiency, offers greater flexibility to truly test the equipment (EUT) under real-world threat conditions, and can be fully compliant to standards.

Dielectric Resonator Oscillators (DROs) are compact, narrowband devices that stabilize frequency with a dielectric resonator, enabling the generation of microwave signals with extremely low phase noise. In this whitepaper, discover an advanced phase noise measurement solution that can capture DRO performance accurately and effectively.

The promise of mmWave spectrum for communications has been realized more slowly than hoped. Simultaneously optimizing for output power, linearity, and efficiency over wide bandwidths is more challenging than expected — limiting system capabilities such as range and data rates. This white paper discusses mmTron's approach to overcoming these challenges.

The superior performance of active/advanced antenna systems (AAS) compared to traditional passive antenna systems (PAS) is driving a transition towards AAS for telecommunications base stations. These AAS are composed of several to even hundreds of antenna elements that, depending on the design, require distinct RF signal chains to the antenna elements.

In 5G and 6G, mmWaves bring the promise of new, high bandwidth frequency bands. Propagation losses and fast fading due to increasingly mobile devices and short wavelengths pose challenges for these new concepts. This paper explores the effectiveness of massive MIMO beamforming at mitigating mmWave propagation challenges using Wireless InSite and its mmWave hybrid beamformer capabilities to transmit data streams to a sedan driving in central Manhattan.

Analyzing co-site interference using electromagnetics simulation solutions requires:

• Accurate determination of the coupling between antennas over a broad frequency range
• Evaluation of the impact of non-linear electronic effects

This white paper describes how to analyze co-site interference on large multi-antenna platforms, modify proposed configurations, and easily eliminate co-site interference problems.

The expansion of electronic and radio frequency technology into almost every aspect of daily life has greatly increased the importance of electromagnetic compatibility (EMC) testing. This educational note discusses the fundamentals of EMC precompliance testing: what precompliance is, why precompliance is important, and how precompliance testing is performed.
