Zusammenfassung: | Rake receiver device has step-down transformer (DC), which converts the signal supplied by the antenna into an analog time discrete signal. A delay system is provided, at whose input, an analog, time discrete signal produced by step-down transformer is applied and has number of outputs. Plurality of amplifier is provided, to which, in each case, a delayed imaging is supplied. A path selector is provided for controlling the plurality of amplifier, and at least a combined capacitor is provided on the plurality of output signal of the amplifier depending on the controlling of the switching of the path selector. A transformer device is provided for transforming the analog time discrete signal on the output side of the combined capacitor into the digital symbols for the base band signal processing. |
