Meeting Biasing Requirements of Externally Biased RF/Microwave Amplifiers with
Active Bias Controllers
by Kagan Kaya
Rev. 0 | Page 1 of 16
INTRODUCTION
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.
This application note provides an overview of bias sequencing
requirements and the effects of using various bias conditions.
It presents an elegant solution for biasing amplifiers using active
bias controller such as the HMC980, HMC980LP4E, HMC981,
HMC981LP3E, HMC920LP5E, and all externally biased
RF/microwave amplifiers.
