The major consistent trend in the satcom industry is the necessity to achieve greater performance while reducing the size of the device. Microwave component design engineers have to balance SWaP for BUCs and SSPAs, and deal with the high heat fluxes involved.

This eBook is a compilation of phased antenna and beamforming technology articles along with contributions from COMSOL on simulation techniques and examples of new antenna arrays and beamforming techniques to help you learn about the tradeoffs and design options in this fast developing area. The articles cover fully digital phased array radars, modeling and simulation examples, new array beamforming technologies, 28 GHz beamsteering antenna array simulation and other related topics.

As the RF spectrum becomes more crowded, the chance for interfering signals greatly increases as frequency bands become very close to each other and sometimes even overlap. There are many techniques from filtering to spectrum sharing to frequency cancelation. This eBook has five articles that cover various aspects of interference. The first takes a look at the Wi-Fi or 5G question – do we need both and how they use the same frequencies in some cases. The second article looks at a new self-interference cancelation method for co-location of radio transceivers so they can share the same frequency band. The third looks at a growing technology for 5G called Dynamic Spectrum Sharing that allows LTE and 5G signals to use the same frequency band. The next article is a short discussion about how the unlicensed bands may become a key factor in the rollout of 5G. The last article takes a look at 5G mmWave filtering and the challenges to designing good filters at these higher frequencies.

As 5G, Wi-Fi 6 and various IoT connectivity standards roll out together, many people wonder how these technologies will work together to benefit businesses and consumers. This eBook presents a number of products and technologies that enable Wi-Fi, IoT and 5G wireless systems to work together without interference. New filter and front-end modules are key products that enable these wireless technologies to work together seamlessly. The first two articles feature Qorvo products that allow these wireless technologies to work together with excellent performance. This is followed by a short update on the release of Wi-Fi 6 and then a thorough article covering the various Wi-Fi and IoT deployment synergies.

Today’s satellite communication systems combine features from legacy cellular networks and emerging wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals.

RF/microwave modules, often referred to as “hybrids,” integrate functional blocks used to transmit and/or receive radio signals. These hybrid circuits combine different technologies, including monolithic microwave integrated circuits (MMICs)/RFICs, discrete field-effect transistors (FETs), and passive devices attached to substrates such as alumina or FR4, which contain circuit traces and distributed components, all within a single housing or enclosure.

Pulse width modulation (PWM) is a commonplace technique for efficiently driving switched mode supplies at a fixed frequency. This applies to many types of power supplies in industrial control systems, power electronics and digital communications.

The MATRICs™ Transceiver is poised to cross over from defense applications to commercial markets with the latest non-ITAR version. The ultra-wideband reconfigurable transceiver system on a chip has immediate applications as a software defined radio prototyping platform for commercial RF/mm-Wave applications, including 5G FR2 and point 2 points links.

Application development in the millimeter-wave (mmWave) frequencies for terrestrial communication, high-frequency device characterization, automotive radar, and other technologies is increasing. The challenge of testing and characterizing the devices that enable new solutions is becoming increasingly complex. As broadband testing over hundreds of gigahertz of bandwidth is subject to repeatability and accuracy deficits, researchers and engineers are demanding better broadband solutions that help to overcome these challenges and simplify mmWave testing.

This white paper provides an overview of the basic building blocks of a phased array system and discusses how the nature of their design leads to a challenging test environment.
