This is the final installment of AR’s blog series “Specifying RF/Microwave Power Amplifiers for EMC Testing.” The full series can be viewed here.
TRANSISTOR
The transistors used in the amplifier are a main component of the amplifier and can provide hints about the design and provide you with another data point in your purchasing decision. Some manufacturers have been using GaN technology in its higher frequency amplifiers for some time now. The benefit of GaN is greater power density than other technologies, which translates into higher power amplifiers and smaller overall packages compared to competitor’s similarly powered amplifiers.
BUILD VS BUY MODELS
Another important point is having the ability to develop one’s own module using die bonding technologies. This has allowed manufacturers to offer continuous frequency range amplifiers from 0.7 to 6 GHz. Not only are these modules beneficial for EMC purposes, but they are also widely used by wireless component and product manufacturers for R&D purposes.
AMPLIFIER REGULATORY COMPLIANCE
Almost always forgotten is the importance of product regulatory compliance. It is crucial for amplifiers to undergo safety, EMC, and hazardous substance evaluations. Although only required in some regions of the world, it is beneficial to make compliance to these requirements mandatory on all newly developed products, thereby reducing potential harm to users and the environment. Many companies use independent third-party laboratories to evaluate products to international safety and EMC test standards, so there is no question about the validity of compliance compared to those manufacturers who choose to perform in-house evaluations.
IN FINAL…
As you can see there are many factors to consider when selecting an amplifier. AR’s Applications engineers have years of amplifier experience in areas such as EMC, wireless component R&D testing, and more, and can help you select the right amplifier for your specific purpose.
