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 are Radio Frequency bands and its uses?

What is Radio Frequency?
RF is the lowest portion in the electromagnetic spectrum familiar as a medium of analog and modern digital wireless communication systems. It spreads in the range between 3 kHz and 300 GHz. All known transmission systems work in the RF spectrum range including analog radio, aircraft navigation, marine radio, amateur radio, TV broadcasting, mobile networks, and satellite systems. Let’s take a look at each of the RF sub-bands and the areas of RF spectrum uses.

How 5G technology works
5G is one of the most discussed technologies in this decade, what is 5G, and how does 5G technology work?

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 more efficient network. On 3rd April 2019, the first 5G service introduced in the US by Verizon. Since then many countries started their 5G deployments.
What is Impedance matching

In electrical engineering, impedance is the ratio of voltage to current with the consideration of phase angle. According to Ohm’s law V= IR, where V – voltage, I is the current and R is the resistance of the network. In RF, the idea of impedance matching is to equalizing the source and load impedance for maximum power transfer. Impedance is represented as Z and is complex than just the resistance of the network. In simple explanation, impedance matching is to making source and load impedance as similar as possible in order to minimize losses.
