Disruptive MMICs for mmWave: Power | Efficiency | Linearity

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.

Effects of Mobility on mmWave Beamforming in Dynamic, Urban Environments

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.

Large Platform Co-Site Interference Mitigation

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.

Cost-effective Front-end Components for X- and Ku-band Phased Array RADAR

This paper looks at common system architectures for short- to medium-range AESA radars, with a focus on the front-end components used to enhance system performance. These components include the power amplifier (PA) for transmit, the low-noise amplifier (LNA) for receive, and the transmit-receive switch to connect the antenna to the electronics. Key features include the different power levels, frequency bands, and compact size required to use these systems in urban areas.
