MODULE FOR RADIO COMMUNICATION

摘要

A module for radio communication in accordance with the Blue Tooth concept and/or in accordance with the wireless-LAN concept, wherein the module comprises a transmitter-and-receiver circuit and an antenna. The invention is characterised in that the module comprises a carrier in the form of a laminated PCB-card (1) (Printed Circuit Board) that includes a number of electrically conductive metal layers (M1-M5) and so-called microvias; in that a first side (11) of the card (1) has an integrated antenna (10) formed in the metal layer (M5) on said side and connected to the remainder of the module; in that a radio frequency chip (13) is surface-mounted on the PCB-card (1) on other side (12) of said card; in that passive components (14, 15), such as filters, Baluns, inductors and capacitors, are integrated in the PCB-card (1) and connected to different microvias; and in that terminals in the form of BGA balls (16, 17) (Ball Grid Array) are provided on said second side (12) of the card.
