A Highway For Spin Waves
A Highway For Spin Waves

The success story of information processing by way of moving electrons is slowly coming to an end. The trend towards more and more compact chips constitutes a major challenge for manufacturers, since the increasing miniaturization creates partly unsolvable physical problems.

    Improving Wireless Network Flexibility Using CPRI Technology

    Traditional cell sites are equipped with a ground-based radio connected to tower-mounted antennas by a long run coaxial cable. These cables have high loss and are vulnerable to interference, which negatively impacts maintenance costs and system performance. Wireless networks have evolved to using a remote radio head (RRH) where the radio equipment is connected to the baseband unit (BBU) by a fiber optic cable. With this new architecture comes the necessity for an equally flexible interface between the BBU and RRH. This white paper presents the Common Public Radio Interface (CPRI) technology that is now used in the majority of new installations.

Carrier Aggregation In Mobile Devices

Carrier aggregation (CA) enables mobile network operators worldwide to provide faster data, and allows mobile devices to communicate on multiple LTE bands simultaneously. This, however, creates the challenge of avoiding interference between the bands while keeping up good reception and battery life. Multiplexers are an excellent solution for CA combinations that use closely spaced bands since they provide isolation between and within bands, while allowing them to connect to the antenna at the same time. This white paper discusses the challenges of carrier aggregation, and the important benefits of using multiplexer solutions to solve them.

GaN MMIC PAs Support The Rapid Growth Of Ku Band Applications

Ku Band has become an essential part of the radio frequency spectrum since it was opened for satellite communications over two decades ago. New systems within commercial satellites use the Ku Band to provide worldwide coverage, which is especially attractive for government and military communications. Since the future of this band generates such a high interest, Wolfspeed, a Cree company, offers Ku Band power products using its proven fabrication process of GaN on silicon-carbide substrates. This white paper discusses the new GaN MMIC PAs and how they are able to support the future growth of Ku Band applications.

Optimization Of Torque In A Permanent Magnet Synchronous Motor (PMSM) For Traction Applications

This article provides a summary of the simulation and optimization of 200 Hz, 8-pole permanent Magnet Synchronous Motor (PMSM) that is typically used for traction applications in automotive and transportation systems.

Modeling And Simulation Of Metamaterial-Based Devices For Industrial Applications

Metamaterials provide great potential for new technology developments, making existing devices smaller, faster, and more efficient. A wide variety of metamaterials produce electromagnetic phenomena that are not seen in natural materials. Simulation can be used when developing new materials to analyze both the bulk property of the material and individual element. This article demonstrates how CTS STUDIO SUITE is used to simulate and design metamaterials from the design of the resonator to the implementation in a full device.

Custom EMI Filters
Custom EMI Filters

EMI Filters are used to prevent electromagnetic interference in avionics and aircraft systems, as well as military shipboard/vehicle electronics, and in military communication systems. Electromagnetic interference can cause a complete loss of data in communications systems, or a simple decline in data quality.
