Coupled Line Couplers — Lesson 4

This lesson covers the construction and functioning of a coupled line coupler, which consists of two pieces of transmission line placed side-by-side. It also discusses the concept of even and odd mode characteristic impedance. The lesson further explores the applications of couplers in network analyzers, IQ modulators, balanced amplifiers, balanced filters, and bias tee.
