Learn About The Active Components In RF Circuits
As with most of the passive components, the active components which are used in RF circuits also share a number of characteristics that are usually found in lower-frequency analog setups or systems. That being said, there are a few components that are particularly specific to the design of the RF. Additionally, numerous semiconductor technologies are often deployed to make sure the RF components offer the best performance at even very high-frequency levels. We discuss some of the most useful active components used in RF boards and circuits. Amplifiers - Amplifier circuits are mostly built around an operational amplifier. These are highly common in both low and high-frequency analog designs. In the case of RF systems, there are two key types of amplifiers that are used. These are low-noise amplifiers and power amplifiers. Power amplifiers increase the power level of an RF signal before the actual transmission. As for the low-noise amps, they are used to amplify the very small...
