Quad-flat no-lead (QFN) is one of the standard packaging technologies used in electronics. MMIC is wire bonded to a pre-produced lead frame. Then, whole package is molded on top with plastic. Having 0.4mm to 0.6mm pitch, it is easy to handle for surface mount technologies (SMT) for assembly printed circuit boards (PCB).
