ABSTRACT:
The invention relates to an improved amplifier switch which for example has the following features: between an in-gate (1; 1.1, 1.2) and an out-gate (3; 3.1, 3.2) an amplifier branch (5; 5.1, 5.2) and at least one bridging line (7; 7.1, 7.2) that can be switched on and off in parallel thereto are provided. At the outlet side, an amplifier branch (5; 5.1, 5.2) is connected to a pertaining bridging line (7; 7.1, 7.2) via a summing circuit or a summing point (17) that is/are linked with the out-gate (3; 3.1, 3.2). The bridging line (7; 7.1, 7.2), between the pertaining switch contact (K1) of the pertaining switch (9; 9.1, 9.2) and the summing circuit or the summing point (17), has an electrical length that corresponds to λ/2.
