Full-wave electromagnetic simulation of a Compact Antenna Test Range (CATR) is not trivial given its electrical size. Typically, the reflector geometry is simulated using asymptotic methods using an assumed feed pattern, while RF absorber and its effects are ignored.

Noise is an ever-present factor that affects the performance of wireless systems. In its broadest sense, noise represents undesired electromagnetic (EM) disturbances that can distort information-carrying EM signals. These distortions can originate from internal sources that are generated within electronic systems, as well as natural or man-made external sources, such as atmospheric noise, cosmic noise, and EM interference.

Getting EMI emissions under control is one of those tasks that R&D engineers do not enjoy doing. EMI must often be taken into consideration as early as the design phase, particularly in the case of power electronics systems with increasing switching speeds of wideband gap semiconductors.

RF inductor selection involves a number of key parameters including, mounting (surface mount or through-hole), inductance value, current rating, DC resistance (DCR), self-resonant frequency (SRF), Q factor, and temperature rating. While small size is typically desired, the laws of physics limit how small an inductor can be for a given application. Inductance value and current rating are the chief determinants of size. Once they have been calculated, other parameters can be optimized.

This white paper aims to provide you with a thorough overview of the major aspects of 5G non-terrestrial networks technology and corresponding challenges. We haveincorporated the latest state of the technology involved, representing the current status of the standardization work ongoing in 3GPP.

One challenge facing test engineers charged to evaluating today’s complicated wireless networks & devices is the sheer number of potential RF connections requiring scrutiny. Readers will learn how RF switch matrices can extend the port count of VNAs to meet the testing demands of modern wireless standards & sensing technologies.

For every mission-critical application, the space qualification and screening process is unique. Download our new white paper to learn more about the common standards and testing processes that will help ensure components are designed to operate reliably in challenging space environments.

A vector network analyzer is an essential tool for the characterization of antennas. This application note provides an overview of near and far-field measurement techniques. There are challenges to either method, and a solid understanding of these will be helpful to achieve superior measurement results.

In this white paper, ERZIA will focus on the Adjacent Channel Power Ratio (ACPR) method which measures amplifier behavior under a specific modulated input signal, which gives a clear indication of amplifier performance for a given application. We then compare this with classical RF parameters of the amplifier.
