US 2019/0245520 A1 · A Balun Arrangement

Abstract

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′).
