Catching Heartbeats With Millimeter-Wave Radar
Catching Heartbeats With Millimeter-Wave Radar

Heartbeats can now be measured without placing sensors on the body, thanks to a new technology developed by researchers at the Kyoto University Center of Innovation, together with Panasonic Corp, who have come up with a way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs.

Multiharmonic Volterra Model Dedicated To The Design Of Wideband And Highly Efficient GaN Power Amplifiers

It is important for future RF communication systems to have high power-added efficiency, high linearity, and wide bandwidths. Amplifiers in today’s base stations consume a lot of power in order to send complex and wideband modulated signals. It is therefore necessary to develop more efficient base stations and power amplifiers to reduce overcrowding, and to overcome low efficiency and the need for device cooling. This paper presents Maury Microwave’s new behavioral model called the multiharmonic Volterra (MHV) model for designing wideband and highly efficient power amplifiers with packaged transistors in computer-aided design (CAD) software.

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.

Microwave USB Power Sensor (MA24106A)
Microwave USB Power Sensor (MA24106A)

The MA24106A power sensor is a USB power sensor that eliminates the need of a traditional power meter. It is designed to provide accurate average power measurements from 10 MHz to 6 GHz over 60 dB of dynamic range. It is a highly accurate, standalone instrument that communicates with a PC via USB or with many of the Anritsu handheld products (often requiring Option 19). The power measurement capability of MA24106A is intended to mimic that of a traditional thermal (thermo-electric) power sensor by providing true-RMS measurements, although the MA24106A offers a wider measurement range. Therefore, it is ideal for measuring average power of CW, modulated RF waveforms such as 3G, 4G, OFDM, and multi-tone signals. True RMS power measurements enable one to make accurate measurements regardless of the input signal type.
