摘要： The embodiments herein relate to a power amplifier arrangement (100) comprising a main amplifier (101) comprising an output connected to a first terminal (110) of a primary winding (105) of a transformer (125). A second terminal (113) of the primary winding (105) is connected to ground (115). The power amplifier arrangement (100) comprises an auxiliary amplifier (103) comprising an output connected to a first terminal (120) of a secondary winding (108) of the transformer (125). A second terminal (118) of the secondary winding (108) is connected to a load (130).

摘要： The present disclosure relates to an amplifier arrangement comprising a first amplifier, a second amplifier and an output combiner arranged to combine respective output signals of the first amplifier and the second amplifier into an output signal of the amplifier arrangement. An amplifier arrangement input signal is arranged as input signal to the first amplifier, and a difference signal, representing a difference between the amplifier arrangement input signal and a scaled output signal of the first amplifier, is arranged as input to the second amplifier. The output combiner is arranged to modulate the loads of the first amplifier and the second amplifier in dependence of the output signal of the second amplifier.

摘要： The present disclosure relates to a balun arrangement (1, 1′, 1″) comprising a single-ended port (2, 2; 17, 26), a differential port arrangement (61), a coupled first and second transmission line section (5, 6) constituting a first coupled pair (7), and a third and fourth coupled transmission line section (8, 9) constituting a second coupled pair (10). The first transmission line section (5) is connected between a first coupled pair first port (11) and the third transmission line section (8), the second transmission line section (6) is connected between a first coupled pair second port (12) and the first differential port (3), the third transmission line section (8) is connected between a second coupled pair first port (13) and the first transmission line section (5), and the fourth transmission line section (9) is connected between a second coupled pair second port (14) and the second differential port (4). For one coupled pair (7, 10), the first port (11, 13) is connected to the single-ended port (2, 2; 17, 26), and the second port (12, 14) is connected to ground. For the other coupled pair (10, 7), the first port (13, 11) is connected to ground, and the second port (14, 12) is connected to open circuit (15, 15′).

摘要： The present disclosure relates to a transceiver arrangement (1) comprising a transceiver device (2) having at least two transceiver ports (8b, 9b, 10b, 11 b), a beamforming network (5), and at least two antenna ports (12a, 12b, 12c, 12d). The transceiver device (2) comprises at least two low-noise amplifier (LNA) arrangements (3a, 3b, 3c, 3d), where each LNA arrangement (3a, 3b, 3c, 3d) is connected to a respective transceiver port (8b, 9b, 10b, 11 b). The beamforming network (5) is arranged between the antenna ports (12a, 12b, 12c, 12d) and the transceiver ports (8b, 9b, 10b, 11 b), whereby a radio frequency (RF) signal received on an antenna port (12a, 12b, 12c, 12d) traverses the beamforming network (5) prior to being received on the transceiver ports (8b, 9b, 10b, 11 b). In a receive mode configuration of the transceiver arrangement, the beamforming network (5) is arranged to provide a beam-forming function, whereby the RF signal received on an antenna port is received on the transceiver ports with specific respective phase shifts.
