Network analyzers are electronic instruments used to measure the characteristics of electrical networks, such as impedance, AC voltage and current, and distortion. RF network analyzers can be used for a variety of applications, such as characterizing filters, amplifiers, and impedance matching networks; measuring noise figure and gain; and troubleshooting RF circuits. Find out some basics of Vector Network Analyzer. [Read more…] about Vector Network Analyzer Basics
Wireless charging has become an essential option for smartphones and mobile devices. What is wireless charging device and how does wireless charging works?
Wireless charging basically charging of mobile devices without using conventional wired connections. It works based on the principle of electromagnetic induction. One pair of coiled wires transfers energy in the form of magnetic flux. International standard for wireless charging is known as Qi wireless charging.

What are RF connectors?
RF connectors are connectors used to make electrical connection for signal transmission in radio frequency applications. These connectors are used in wide variety of applications range from 0 to 18 GHz and above.
All types of RF connector have one male connector and one female connector. Male connectors are often called plug and female connectors as jack. Center pin and outer grounding with locking mechanism provides it a strong and reliable connection. [Read more…] about Most common RF connectors and its applications
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.
