CST MICROWAVE STUDIO®’s Integral Equation solver is a new module for the accurate 3D analysis of electrically large structures. It is based on the Multilevel Fast Multipole Method (MLFMM) and is used for antenna coupling and radiation pattern analysis. Typical applications include antenna placement on aircrafts and radar cross section (RCS) calculations of large scattering objects.
Orthogonal frequency division multiplexing (OFDM) is a form of digital modulation used in a wide array of communications systems. This paper will explain what OFDM is, why it’s important, where it’s used, and what test instrumentation is required to maintain it.
Michael Millhaem, Principal RF Application Engineer Keithley Instruments, Inc. Test equipment manufacturers are constantly challenged to develop new solutions for testing their customers’ latest devices, but they’ve traditionally developed specialized hardware to meet this challenge....
True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field strengths and more. What is a decibel and how should we use it in our calculations? This Application Note is intended as a refresher on the subject of decibels.
