Title:
アンテナ分岐
Document Type and Number:
Japanese Patent JP4340010
Kind Code:
B2
Abstract:
The invention relates to an integrated circuit (1) for receiving high frequency signals which enables a reduction of fault capacities. High frequency signals of a lower receive frequency range (5) and of an upper receive frequency range (10), especially of an AM/LMK radio frequency range and of an FM/UKW radio frequency range, can be received using the inventive integrated circuit (1). In addition, high frequency signals of a radio frequency range (15), especially of a GSM radio frequency range, can be received and transmitted. To this end, the integrated circuit (1) can be connected to an antenna which is common for all three frequency ranges (5, 10, 15) and which is not tuned to the lower receive frequency range (5). A first terminal (20) of the integrated circuit (1) can be connected to a base point of the antenna. The radio frequency range (15) is above the upper receive frequency range (10). A first circuit branch (25) for decoupling the high frequency signals of the lower receive frequency range (5) is provided on the first terminal (20). In addition, a second circuit branch (30) for filtering the high frequency signals of the upper receive frequency range (10) and of the radio frequency range (15) is also provided on said terminal.
