==Transmissionslinjetransformator==
En '''transmissionslinjetransformator''' er en transformator, somder formidlerbenytter energitransmissionslinjer mellem to transmissionslinjersom typisken meddel forskelligeaf impedanserdesignet.

* '''Ruthroff-transformator''' (impedans 1:4) - fra en ubalanceret transmissionslinje til en anden (unun). Ruthroff-transformatoren blev offentliggjort i en artikel af C.L. Ruthroff i 1959.<ref>Ruthroff, C.L., "Some Broad-Band Transformers", Proc IRE, Vol 47, August 1959, pp. 1337-1342.</ref>
* '''Guanella-transformator''' (impedans 1:4) - fra en balanceret transmissionslinje til en anden (balbal). Guanella-transformatoren blev offentliggjort i en artikel af George Guanella i 1944.<ref>Guanella, G., "Novel Matching Systems for High Frequencies", Brown-Boveri Review, Vol 31, Sep 1944, pp.327-329.</ref>
