Abstract: A radio frequency chip package is formed by assembling a connecting element such as a circuit board (52) or flexible circuit tape having chips (72, 84) thereon with a bottom plane element (20) such as a lead frame incorporating a large thermally-conductive plate (22) and leads (40, 42) projecting upwardly from the plane of the plate. The assembly step places the rear surfaces (78) of the chips (72) on the bottom side of the connecting element (52) into proximity with the thermal conductor (22) and joins the conductive traces (60) on the connecting element with the leads. The resulting assembly is encapsulated, leaving terminals at the bottom ends (45) of the leads exposed. The encapsulated assembly may be surface-mounted to a circuit board (102). The leads (40, 42) provide robust electrical connections between the connecting element (52) and the circuit board (102).
