<p>Device (5) comprising load lines (3) coupled to outputs of amplifier stages (1) are provided with controlled matching stages (10) for matching the load lines (3) to the amplifier stages (1). Further controlled matching stages (11) matching antenna stages (2). The controlled matching stages (10,11) comprise deriving means (20,30) for deriving signals from the load lines (3), detecting means (40,50) for detecting signal parameters of the signals, and controlling means (60,70) for controlling adjustable impedance networks (14,15) in response to said detecting for said matching. The deriving means (20,30) comprise first (21) and second (31) elements, the detecting means (40,50) comprise first (40) and second (50) detector systems coupled to the elements (21,31), and the adjustable impedance networks (14,15) comprise first (14) and second (15) adjustable impedance networks controlled in response to detections performed by the detector systems (40,50). The detector systems (40,50) comprise peak detectors (41,51,42,52) for detecting peak information and phase detectors (43,53,45,55) for detecting phase information.</p> |
