This primer outlines the basics of RF power sensors and highlights a few key characteristics that will help you select the best one for each application. The educational note has three parts: choosing the right type of sensor, attributes of sensor performance, and we outline three ways to integrate a sensor into your measurement application.

This white paper discusses the importance of EM analysis and highlights various Cadence® EM solver technologies for high-frequency system design. Specific application examples showcase the benefits of using these technologies integrated within the Cadence AWR Design Environment® platform, specifically Microwave Office® circuit design software.

RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. Many wireless technologies are based on RF field propagation and RF energy is incorporated in a multitude of applications, from telecommunication to non-communication applications and medical purposes.

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.

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.

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.

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.

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.

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.

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.
