IIoT Sensor Network Cable Solutions for Wireless Power Transfer

Building an Industrial Internet of Things (IIoT) sensor network requires additional costs, with more than 60% of these costs related to wiring and installation. While wireless data transfer can help eliminate some cable connections, even more wiring can be avoided by adding wireless technology for power transfer. Startup TransferFi is working on a new wireless […]

A Brief Introduction to System-Level Characterization and Modeling Techniques for Radio Frequency (RF) and Microwave Subsystem Components

This application note describes system-level characterization and modeling techniques for radio frequency (RF) and microwave subsystem components. It illustrates their use in mixed-signal, mixed-mode system-level simulation. This simulation uses an RF transmitter with digital predistortion (DPD) as an example system. Details of this complex system and performance data are given. introduce The radio frequency (RF) […]

Analysis of the optimization scheme of grounded coplanar waveguide RF feeder

The Signal Integrity Group at Arira Design was asked to redesign the existing 5GHz grounded coplanar waveguide RF feedline to improve the performance of the Wi-Fi subsystem on the customer’s board. Measurements show that the impedance of the feeder impedance is about 38 ohms. Before simulation, the original design identified several issues, including: Unable to […]

Digital Radio Frequency Memory (DRFM) Applications in Electronic Warfare Systems

Electronic warfare systems are typically deployed on ground, sea, and airborne platforms to maintain strategic and tactical advantage on the modern battlefield. As the threat environment evolves, there is a growing need to integrate advanced electronic warfare capabilities in precision-guided weapons (PGWs), which are demanding size, weight, and power (SWaP) platforms, bringing today’s defense microelectronics […]

How does the RF carrier signal turn the wave into a signal carrier?

When using Wi-Fi inside a building, some signals hit the receiving antenna directly, while others bounce off walls or other objects, creating RF echoes. In this small series we generally discuss RF carrier signals, especially Wi-Fi (see also Fundamental Concepts, Electromagnetic Radiation, Wave Mechanics I and Wave Mechanics II). How do we actually send the […]

Antenna Design: Ground Plane and Board Design for RF

By: Geoff Schulteis of Antenova When the product is wireless and requires additional antennas, the design cycle is different. Antennas change the design process, since it must be carefully placed in the optimal location on the PCB, it is important to consider how the antenna relates to some other components in the design. Ideally, designers […]
