Main Content

Cascaded Subsystems

2-port amplifiers, mixers, and lumped-element passive filters; series and shunt resistors, capacitors, and inductors; coaxial, waveguide, microstrip, parallel-plate, RLCG, and two-wire transmission lines

You can use the 2–port behavioral models for link budget analysis. In this library, frequency-selective components are described as either lumped and distributed elements or as S-parameters.
