I have not posted for a long time! Not only because I was too busy in the meantime, but also because I was working on a quite involved project: a new GPSDO!

Lumped element quarterwave transformers
Everybody knows that a matching network can be built using a quarterwave transformer. E.g. if a load of impedance \(Z_L\) shall be matched to a source having impedance \(Z_S\), this can be accomplished by using a transmission line with an electrical length of 90 degrees and characteristic impedance \(Z_0 = \sqrt{Z_S\,Z_L}\). However, is this also possible using lumped elements?
