RF CAREER GUEST COLUMNS
This year’s batch of Nobel Laureates all seem to be fine scientists, researchers, authors, and leaders who don’t seem to have anything to do with Halloween. But don’t worry, we found some past award winners who do!
Ensuring Reliable Bluetooth Low Energy Performance In Wearables, IoT Devices
Good design, development, and product testing are key to ensuring functionality, reliability, and continued sales growth. Testing is an important consideration through a product’s entire life cycle in order to find and fix problems before they become truly expensive.
Bluetooth Low Energy 101
This two-part article will provide product designers with the information they need to develop quality Bluetooth low energy products, starting with an understanding of the standard.
RF CAREER DEVELOPMENT ARTICLES
Filter Terminology And Specifications
This guide acts as a quick reference for terms used to discuss filter technologies.
Common Applications For Radio Frequency (RF) Filters
An RF filter permits a signal of interest to pass through while attenuating any undesired signals. This article describes the different filter shapes, or responses, when plotted in the frequency domain, defines general terms in filter utilization, and covers common types of applications that use RF filters.
The Basics Of Quadrifilar Helix Antennas
The ability to receive or transmit a tight beam of circularly polarized radiation while minimizing unwanted radiation is imperative to good communication. For such applications, the axial-mode quadrifilar helical antenna provides high performance and a robust platform, both in space and on the ground.
RF CAREER DEVELOPMENT INTERVIEWS
Role Call: Senior Staff Packaging Engineer
Role Call, a series on RF Globalnet, takes a “peek behind the curtain” to help answer the questions related to different jobs and career paths in the RF and microwave industry. Recently, Mumtaz Bora, Senior Staff Packaging Engineer at pSemi, took time to answer some questions about her occupation.
Role Call: RF Modeling Manager
Role Call is a new series on RF Globalnet that will look at different jobs and career paths in the RF and Microwave industry. We’ll explore what each position entails, how much you have to know, and what experience you need to get started. Yueying Liu, RF Device Modeling Manager with Wolfspeed/CREE has held various positions in the industry since earning her doctorate in solid-state electronics from North Carolina State University in 2009. Liu’s experience ranges from GaN product engineer and modeling design engineer to RF PA designer and RF modeling engineer, before taking her current management role last year.
Role Call: Consultant Engineer
Role Call is a new series on RF Globalnet that will look at different jobs and career paths in the RF and Microwave industry. We’ll explore what each position entails, how much you have to know, and what experience you need to get started. The first position we have explored is a consultant engineer. Andy Dearn, the Principal Consultant Engineer at Plextek RFI Ltd., let us take a peek behind the curtain, revealing everything from the most exciting aspects of his job to the mundane day-to-day activities.
CAREER DEVELOPMENT WHITE PAPERS AND APPLICATION NOTES
This white paper offers the reader a basic understanding of electromagnetic interference (EMI) and compatibility (EMC), various compliance standards and specifications, types of testing available for quantifying equipment performance, and basic approaches utilized to help meet application requirements.
A programmable or step attenuator is externally controlled with maximum attenuation ranges from 0 dB to 127 dB, in steps as small as 0.1 dB. This app note discusses key components in a programmable attenuator system, as well as the best choices for general applications.
Power inductors typically are used for energy storage in DC/DC converters or high-noise filter applications, including motor speed control, adjustable lighting, DC power conditioning, and more. This article delivers the basic information for understanding power inductors, their uses, and benefits.
This application note provides an introduction to the practical uses of RTSAs to reveal important information about the performance of RF/microwave components, track down sources of interference, and monitor the spectrum for activity and security threats.
