# Application Example: Quarter wave transformer

#1

Quarter-wave transformers are used to match a load impedance with a transmission line in order to minimize reflections.

In this example, a 350 Ohm is matched to a 100 Ohm microstrip line. The load is represented by a 2D RLC lumped element. The bandwidth is also analyzed
