S-parameters are one of the most important information regarding any passive or active component for RF design, simulation and analysis. To ensure the accuracy and quality of the complex system, RF engineers often deals with S-parameters of many devices and components.
Let’s take a look on some of the free and useful tools for S-parameter plotting, analysis, simple active circuit design and impedance matching.
What are S-parameters?
S-parameters are the electrical characteristics of a signal in a complex network. It is also known as scattering parameters and mostly used in RF network and applications. Vector Network Analyzer is used to measure and analyze signal behavior of S-parameters. The signal behavior can be observed as gain, return loss, VSWR, reflection coefficient and group delay etc.
What is Radio Frequency?
RF is the lowest portion in the electromagnetic spectrum familiar as a medium of analogue and modern digital wireless communication system. It spreads in the range between 3 KHz and 300 GHz. All known transmission systems works in the RF spectrum range including analogue radio, aircraft navigation, marine radio, amateur radio, TV broadcasting, mobile networks and satellite systems. Let’s take a look on each of the RF sub bands and the areas of RF spectrum uses.
RF attenuators are one of the most significant components in any RF and microwave systems. What are RF attenuators and what is the purpose of it? Here I would like to share about the basic construction, types, use and what are the important factors to choose a proper attenuator for your next RF application.
5G is one of the most discussed technologies in this decade, what is 5G and how 5G technology works?
5G is the fifth generation telecommunication and wireless network standard which will be capable of handling greater data rates and network efficiency. 5G networks will offer scalable and adaptable services, it promises a smarter, faster and efficient network. This new system expected to be launched in early 2020s.
