  • Patent number: 7174132
    Abstract: The invention relates to a circuit arrangement in association with the RF unit of a wireless terminal, in which circuit arrangement the RF unit and the antenna (3) of the wireless terminal are fabricated/mounted on the same circuit board (1) and where the antenna (3) is connected to the RF unit through at least one signal line (2). In the circuit arrangement, the signal line (2) from the RF unit to the antenna (3) is electrically connected during the final assembly by means of a jumper (5) which is fabricated as part of a mechanical component (6) belonging to the terminal. With the arrangement according to the invention, the RF unit can be tested without interference from the antenna.
