How to Measure and Reduce Common Mode EMI in Electric Drive Installations

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.

How to Increase Downstream Bandwidth and Upstream Capabilities in CATV Amplifiers with Greater Efficiency

Staying relevant in the CATV market can be challenging with fast-changing standards and regulations. Hybrid fiber coaxial (HFC) networks worldwide are being upgraded to DOCSIS® 3.1 (data over cable service interface specification) with a mid- or high-split to enable increasing data speed and capacity for upstream and downstream traffic.

Understanding the Basics of RF Signal Generation

RF signal generators have been a staple in test and measurement for more than a half century. During that time, they have evolved significantly, but the underlying principles remain the same. This whitepaper provides an overview of the basic construction of RF signal generators and the associated figures of merit.

Accurate Electric Field Measurement with the Vector Field Analyzer

New wireless devices require fast, accurate, and complex electromagnetic field measurements. Product and test complexity constantly drive increased speed and accuracy in electrical, time, and even spatial domains. The Vector Field Analyzer is a new instrument that connects these domains, meeting the demands of leading-edge development and production testing.

3D Printed Dielectric Lenses Increase Antenna Gain and Widen Beam Scanning Angle

RF markets are demanding greater performance for wireless links and sensing applications. Active Antenna Systems are the incumbent solution, but come with high cost and complexity. This white paper demonstrates how polymer dielectric 3D printing is used to create higher performance RF devices that can reduce complexity and cost of RF systems.

Highly Integrated Transceiver with RF Front End Reduces Design Time and Development Resources

Richardson RFPD engineers and others have teamed with Analog Devices to introduce a highly-integrated transceiver and have built SoMs and RF front ends to interface with it. Our goal is to provide engineers with small, low-power, high-performance starting points that will reduce design time and the amount of needed resources.

Reliable and Flexible Simulation of Angle of Arrival (AoA)

Engineers often need to test the direction finding capabilities of radar warning receivers in the lab. A perfect solution is to use multiple coupled R&S®SMW200A vector signal generators that are phase-coherent and time-synchronized. This setup enables simulation of the angle of arrival (AoA) of radar signals in the lab.

A Comprehensive Way to Use Bonding to Improve RF Performance of Low Noise Amplifiers

Is RF engineering a form of black magic? This article analyzes the challenges faced in the development of ADH519S, an 18 GHz to 31 GHz low noise amplifier (LNA), for the aerospace market. The die used in the product development for space was originally released to the commercial industry in the LC4 package.
