Circuit Modeling of Coaxial-Cable Baluns in Microstrip-Mounted, High-Power, Very-High-Frequency Amplifiers [Application Notes]

Abstract

Baluns have been studied for several decades. They have been used in antennas as unbalanced-to- balanced signal convertors and have sometimes taken on the role of impedance transformers. Apart from their use in antennas, baluns can be found across a variety of applications, ranging from mixers and samplers to power dividers and amplifiers. Good reviews of the most common balun types can be found in [1]â\x80\x93[3].
