An energy-saving method for wireless reception of data modulated on a carrier signal is carried out in a receiver circuit including a first group and a second group of circuit elements. The first group of the circuit elements required for recovering the data from the modulated carrier signal are supplied intermittently with electrical energy, while the remaining circuit elements of the second group are supplied with uninterrupted electrical energy. After an intermittent unpowered phase without electrical energy being supplied to the first group of circuit elements, the receiver can be operated in the next intermittent powered phase of the second group of circuit elements with parameters that determined the receiver properties which were present in the last reception phase and that have been stored, thus eliminating the time required for renewed tuning in.

The invention relates to an opto-electronic component having a narrow aperture angle. The conventional design of components transmitting radiation or reacting to radiation and concentrating that radiation with the aid of lenses results, on account of the increasing distance between the lens and the semiconductor chip, in increasing component dimensions in the radiating or detecting direction with an increasingly narrow aperture angle. In accordance with the invention, a parabolic or approximately parabolic reflector is provided that is connected to a support strip supporting the semiconductor chip such that the latter is as close as possible to the focal point of the parabolic or approximately parabolic surface of the reflector. The reflector is preferably connected to the support strip by engaging elements and surrounded by a housing.

A semiconductor assembly with a metal frame configuration is described, having a semiconductor component (HL) on a carrier section (T) of a ground strip section (M). The ground strip segment has an extension section (V) with which it is extended beyond said carrier section and is both folded over in relation to said carrier section and of sufficient length that it covers said semiconductor component in order to shield it electromagnetically. In this assembly, the ground strip section has a multiple function. It is used not only for carrying and contacting of electrical components, but also acts at the same time as electromagnetic shielding for a semiconductor component, for example for the radiation detector of a remote control reception module. This shielding is dependably connected to ground since it is formed as one piece with the ground line, it is simple to manufacture since no special connecting operations are necessary, and it is space-saving since no space is required for stable connection points between the shielding and other parts of the assembly.
