Sometimes there is charm in a simple emitter follower, notwithstanding that biasing a simple transistor to compensate for the diode drop seems to be vanishing knowledge. You would want an Ft around 1.5 GHz or a bit higher and layout to match, but not lots higher unless you are into impromptu oscillator design. Stability will depend on proper termination. Are you sure you wouldn't prefer a gain of 2 with a backmatch resistor in series?
