Intermodulation-distortion

Intermodulation is a phenomenon of combining undesired frequency components within an active system or from an external source.  Combination of two or more signals will create another signal which may fall into another frequency band of the system and cause interference to the system. How does intermodulation distortion occur, what are the causes and how to prevent it?

Power amplifiers are significant equipment in every RF communication systems. Similar to other amplifiers, RF amplifiers are also used to provide amplification to the signals supplied to its input. In modern wireless communication systems, the signals are complex due to complex modulation schemes. Amplifier selection is a challenging task for engineers due to many of its important characteristics and specifications.
Here let’s take a look on the most important specifications and how to choose a suitable RF amplifier for your next application.

rf-isolatorRF isolators and circulators play an important role in many RF communication systems. Electrical behaviour of each individual unit contributes to overall system performances. Engineers often monitor and test each component during troubleshooting of an RF system.

RF Isolators: are two port passive devices used in RF and communication networks to allow transmission in one direction and give maximum signal isolation in opposite direction.

What are S-parameters?
vector network analyzer
 
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.
