Avoiding RF Interference with Simulation

Any time that multiple RF systems are co-located, there is an opportunity for RF interference (RFI) to degrade or disrupt the performance of receivers. The impact of RFI includes decreased performance, delayed product releases, product recalls and safety-critical scenarios. RFI is a very serious matter that must be addressed throughout the design of products and systems.

Satellite 2021 Flat Panel Array Technology Review

One of the biggest innovations being deployed for satellite communications systems is flat panel beamsteering arrays that will replace mechanically steered dish type systems. These beam steering arrays are low profile and lighter that previous systems. The main problem has been getting the cost down. We saw many companies at Satellite 2021 that are battling for this market using several different approaches.

New 4D Automotive Radars Hitting the Market

Promising near LiDAR resolution, enabling fully autonomous vehicles and other sensing applications

There has been a lot of activity recently around next generation radar sensors for automotive applications. These newer “4D radar” units determine an object's location in range, azimuth, elevation, and relative speed to provide detailed information about the driving environment as earlier automotive radar systems only captured speed and azimuth. These new radar sensors provide better resolution than previous versions which is where Lidar excels. Here are some of the latest developments in this area.

Concerning PCBs and the Transition from Microwaves to Millimeter Waves

As readers learned in the first part of this two-part ROG blog,1 printed circuit boards (PCBs) can be made for millimeter-wave frequencies by considering circuit-material characteristics when making the transition upward from microwave to millimeter-wave circuits. This second part of the blog explores how different circuit technologies often used at microwave frequencies and different circuit materials handle higher-frequency, millimeter-wave circuits.

The Analog-of-Things Rise is the Crucible of digital innovation

It isn’t news to any professional in the electronics industry, or virtually any other, that almost any technology, process, or service that can be internet or intranet connected is being connected. If it is a wired connection or a wireless connection, the fundamental way most people are interacting with their world or data is being done with, or enhanced by, connected devices. The heart of innovation is effective and accessible communication. The Internet of Things (IoT) has made it possible for devices to relay information one to another, but intrinsically relies on an analog backbone to operate.
