yes, indeed but I haven't other informations!Without part numbers, it's difficult to say.
Maybe.Its a high frekans transistor. Mostly using for high power rf senders. Driving hf antennas.
Maybe an indication here (davenn)Maybe.
But, we do not know the size of the thing, there is no scale.
I am guessing that it is a small signal transistor for use in a receiver rather than a transmitter PA stage.
