Whether we’re pitching to investors, networking at a trade show, or giving a conference presentation, our message impacts the results. If we’re not thoughtful about how we structure that content, select details, and deliver the information, it’s easy to lose the quality and clarity of our communication.
A radio frequency (RF) filter is a special circuit that 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.
RF Globalnet's Role Call series offers a “peek behind the curtain” at different jobs and career paths in the RF and microwave industry. Our most recent subject is Tom Offer, a Senior Hardware Engineer with CommAgility. Tom’s experience has included work with embedded systems, FPGA, and digital signal processing within RF, LTE, telecommunications, and other wireless markets.
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.
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.
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.
This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.
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.
