'Gate' is a direct loanword from English. In German, it is used with the neuter article 'das'.

The two meanings are clearly separated by context. Words like 'Flughafen' (airport), 'Flug' (flight), 'Passagiere' (passengers), or 'Boarding' (boarding) point to the airport gate. Terms from technology or computer science point to the logical circuit.

Passengers for flight LH245, please proceed to Gate A15 immediately.

exit / outcome
'der Ausgang' and 'das Gate' can both have to do with a place at the airport that passengers pass through to continue on. 'der Ausgang' is general: it leads out of a building, room, or area. 'das Gate' is much more specific and refers at the airport to the gate where you board the plane. Learners may confuse the words because a gate can seem like a special kind of exit. But the natural distinction is: at the airport, for the flight to the plane you say 'Gate'; for the door to the outside, you say 'Ausgang'.
