Your bias supply looks suspicious to me, I don't see suffient measures to decouple the solder pad from the RF line.

Newbies often simulate with a voltage source  (=RF short) at that node, but the real world supply line are very different from an RF short. Did you check how isolation from the RF line (transistor input) to the DC pads? I wonder if your spike is oscillation due to RF feedback across the red DC wires which seem to touch each other.
