What is this device? "MCL 0 322", followed by "ADT 1-1W"?

It has 6 legs, corn yellow, approximately 0.8mm X 0.5mm X 0.3mm,
the two rows of text are
"MCL 0 322"
"ADT 1-1W"
"."

Third row has a dot. I found two of this device on my 105MS ADC board,
while on another piece of board, somebody took off this chip. This makes me
wonder what the purpose of this chip is.

Hope you could help.

It's a 1:1 transformer from Mini-Circuits. Look at:

It's the very first entry on that page.

Thank you Jeroen. I think it is the correct device.
