As proven a week ago by my definition quotations from

I shall not try to pop the bubble of your glory in the triumph of
knowing the correct terminology.


But I still shy away from matching impedances with a "choke".
I would match impedances with a balun or RF transformer.


Jerry Sevick, W2FMI, says a *balun IS a choke* plus
a transmission line. He wrote in "Building and Using
Baluns and Ununs":

"If the writers had accepted the correct model for
these devices (given to us by Guanella and Ruthroff),
which shows that *they are really chokes* (lumped
elements) and configurations of transmission lines
(distributed elements), ..." (emphasis mine)

The lumped element equivalent of the transmission line itself is a
repetitive pattern of inductors and capacitors. If all inductors are
chokes, then the transmission line itself is composed of chokes.
