What is the linearity? 2021-01-08

Linearity is an essential standard for a power amplifier(PA) determined by the transistor's property. It can directly impact PA and decide if it can work adequately in RF systems. Of course, it will have a specific requirement in different projects and strategies and, finally, reflect on the amplifier's output ability and characteristic performance.

The Many Frequencies of RF Communication 2021-02-26

There is only one electromagnetic spectrum, but by using different carrier frequencies, numerous RF devices can coexist. The world of RF is a world of frequencies. This is true within a single system or even a single PCB, considering that one RF design may involve signals in multiple frequency ranges. But at this point we want to look at the broad context in which a particular RF system exists; the name we give to this concept is “the electromagnetic spectrum.”

RF Transmission: Regulations, Interference, and Power Transfer 2021-03-04

Learn about how to transfer maximum power from your amplifier to your antenna, and how to estimate this power using an oscilloscope. An important characteristic of RF technology is the following: it is relatively easy for one person to impede, or even thoroughly ruin, another person’s wireless communication. Radio waves travel through the air and are available to everyone, including those who—intentionally or accidentally—are transmitting signals that could be described as interference.

The factors that influence the effect of a signal jammer 2021-03-26

The different radio system has different coding, modulating network organization and channel bandwidth. the best interfering technology is different for the different radio systems, but they have complicated technology, a long-developing period and high price. VCO is a popular and low-cost choice, but also with an effective result for most radio systems.

The basic theory of a basic jamming system 2021-03-30

The basic theory of a jamming system is that when the target receiver(handset devices, walkie talkie, IED, drone, etc.) receives an "effective interference signal" more than the "original signal" 6dB to 20dB in the target channel and location, at this time, target receiver can be jammed.
