Can the circuit oscillate at 10 GHz? How did you arrive at the dimensioning?
--- Updated ---
It actually does oscillate in LTSpice simulation with Infineon SPICE model (including package). The circuit is however completely unrealistic because it doesn't reflect parasitic circuit elements, particularly at emitter node.
