Fundamentals Of Radome And Bumper Measurements Using The R&S QAR

Radome testing is a necessity, checking sensor components for radar compatibility. Previously, there were two methods used for testing. R&S introduces the R&S QAR as another solution. 

XFdtd Simulation Of A mmWave On-Chip Cylindrical Dielectric Resonator Antenna For WPAN

This example demonstrates how XFdtd simulates a 60 GHz cylindrical dielectric resonator antenna that is constructed on a silicon base to emulate on-chip designs. The antenna could be used for a wireless personal area network (WPAN), which would provide communication in the immediate vicinity of a user’s workspace. The antenna has a peak gain of about 2.5 dBi, a bandwidth of over 2.5 GHz, and positive gain of about +/- 55 degrees off boresight.

Out Of This World: Solid State PAs Help Power Space Exploration

Observations run approximately 6,500 hours each year and findings are used in chemistry, physics, radar receiving, and astronomy. Most notably, some discoveries are helping to prove Einstein’s general theory of relativity by examining the high masses and short rotation periods of pulsars. 

Simplifying The Transition From 5G Operations At Sub-6GHz To mmWave

There are three key differences between sub-6 GHz and mmWave operations. There are also a variety of different RF design challenges at mmWave largely because as frequency increases, wavelength decreases.

Find The Right Channels With Switch Filter Banks

Switches and filters are electronic components used in many RF/microwave systems, such as transmitters and receivers. Each provides functionality to aid high-frequency systems, but the functions can also be combined into switch filter banks to save size, weight, and power (SWaP) when miniaturizing a system.

Why Millimeter Wave Requires A Different Approach To DPD, How To Quantify Value

The purpose of this article is to draw a comparison between a traditional sub-6 GHz macrocellular and a mmWave base station radio and antenna design. It further covers how these design differences impact DPD implementation in mmWave arrays relative to sub-6 GHz radios.
