Title:
DISTRIBUTION OF RADIO-FREQUENCY SIGNALS IN AN ELECTRONIC CIRCUIT
Document Type and Number:
WIPO Patent Application WO2004100359
Kind Code:
A3
Abstract:
The invention relates to the distribution of a radio-frequency signal to various modules (20, 30, 40) on a printed circuit board (10). The radio-frequency signal supplied via an antenna plug (11) is led over a multi-section (12, 13, 14, 15) line, a respective decoupler (32) being inserted between two sections (13, 14). In addition, between two sections (13, 14) an amplifier (33) may optionally be provided for compensating for signal losses, and/or a switch (34) for separating non-active modules.
