Meeting Biasing Requirements Of Externally Biased RF/Microwave Amplifiers

By Kagan Kaya, ADI

Radio frequency (RF) and microwave amplifiers provide their best performance under specific bias conditions. The quiescent current established by the bias point affects critical performance metrics such as linearity and efficiency. While some amplifiers are self biased, many devices require external biasing using multiple supplies that must be sequenced properly for safe operation.
