Ultimate guide to choosing an RF power amplifier

Last Modified: April 15, 2017 by Rajiv 2 Comments

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.

How to test an RF Isolator and Circulator

RF 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?

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.
