Abstract: “Do’s and Don’ts” in the application of high-power RF amplifiers in EMC test systems.
RF amplifiers are often thought of as simple devices used to increase signal strength. While it is true that fundamentally all amplifiers have at least one input and output and increase the input signal strength to a level required by the specific application, there are a number of factors that must be considered to properly utilize a modern RF amplifier in a test system.
EMC testing applications represent some of the most extreme environments that RF amplifiers are called upon to operate within. Furthermore, RF amplifiers constitute a large portion of the overall cost associated with large EMC test systems. For these reasons it is incumbent for users to fully understand the nuances of proper RF amplifier installation, usage, as well as safety concerns to extend the life of the amplifier and provide the most accurate, repeatable test results.
This presentation provides guidance in the application of high-power RF amplifiers in EMC test systems.
Amplifier Discussion Topics:
· A review of amplifier technologies, highlighting their respective advantages and disadvantages
· The importance of signal input levels
· The significance of the load impedance and the impact on amplifier performance and output power
· The optimum way to monitor and record RF power
· Typical installation concerns
