RF transceiver arrangement, terminal employing the arrangement, and method for fabricating terminal according to the arrangement
First Claim
1. A circuit arrangement associated with a RF unit of a wireless terminal for testing the RF unit prior to final assembly, in which circuit arrangement the RF unit and an antenna of the wireless terminal are fabricated/mounted on a common printed circuit board and in which the antenna is arranged so as to be connected with the RF unit through at least one signal line, where in said signal line is at least one break and that the signal line is arranged to be connected across the break by means of a jumper during the assembly of the terminal.

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.
