Abstract:
A data receiver circuit for infrared signals comprising several infrared detectors (5a, 5b to 5n) the signals of which are supplied to a summing circuit (7) to increase the useful power while suppressing interfering signals, characterized in that several input circuits, each having an infrared detector (5a, 5b to 5n) and an associated separate transistor amplifier (19a, 19b to 19n) are provided, the transistor amplifiers (19a, 19b to 19n) being connected in emitter connection, each with photodiodes, as infrared detectors, connected in parallel to emitter resistors (18a, 18b to 18n), their collectors being connected via coupling capacitors (25a, 25b to 25n) so as to form the summing circuit with a common connection point (26).
