This white paper introduces some of the fundamental theory behind beamforming antennas. In addition to these basic concepts, calculation methods for radiation patterns and a number of real world measurement results for linear arrays are shown.

In this White Paper Knowles Precision Devices reviews some of the areas of 5G communications that will be implemented in the millimeter wave (mmWave) region of the RF spectrum and provides a guide to available RF filtering options at these frequencies.

When analyzing the signal integrity performance of DDR interfaces, separating read and write cycles has been a challenging task. Comprehensive trigger capabilities are required – especially when attempting to recreate the eye diagram in realtime.

This white paper will discuss an approach and architecture that will improve linearity for solid state high power RF and microwave amplifiers by orders of magnitude, whether class A or class AB topologies, although the fundamental principles can also be applied to TWT and MPM amplifiers as well.

RF modules offer a large amount of functionality in a small space, but they can be an engineering challenge for development teams. When combining multiple integrated circuits (ICs) into a single package, it is necessary to model the electrical behavior of many different technologies, such as interconnects (transmission lines) and embedded distributed components, as well as RF, analog, and digital components.

Beamforming using phased array antennas is a common technology for radar and electronic warfare in the aerospace and defense industry. In satellite communications and 5G NR, phased array beamforming is becoming a default concept. Get deep insights about beamforming with our solutions.

Aperture tuning is essential in enabling smartphones to operate efficiently over increasing RF frequency bands and support transitions to 5G. Proper tuning enables antennas to operate efficiently on multiple bands and increases Tx and Rx performance. Implementing aperture tuning requires in-depth knowledge of how to apply the technology for smartphone application.

The challenges in testing EMI during early product cycle are multifold. In our free step-by-step guide, we break down the whole EMI design test process into “Locate”, “Capture”, and “Analyze”. With this guide, you are now able to discover and analyze EMI in a more systematic and methodical approach.

A phased-array antenna is made up of multiple individual radiating elements (antennas), each fed with an RF signal controlled through phase shifters in such a way that the radio waves from the separate antennas are added together to increase the radiation.

Modern wideband microwave systems often require a flat overall gain response with respect to frequency. Achieving this performance can be difficult, however, since most wideband microwave components exhibit a negative gain slope as the frequency increases.
