As consumer demand for data bandwidth grows worldwide, service providers face difficult and expensive challenges to expand capacity and coverage. Multi-gigabit Fixed Wireless Access systems offer a solution for overcoming many of these service-provisioning challenges.

Today’s test systems are often developed in silos – specific test systems designed for the specific products or processes needed today – without forethought toward future testing needs. However, shifts in demand require today’s products to scale in production or grow in functionality.

This whitepaper explores the innovative concept of passive radar and its many advantages. We cover its operating principles, basics of bistatic radars and the concept of EoOs. We also evaluate the role of satellite illumination and forward scattering in passive radar and highlight real-world examples of operational passive radar systems.

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.
