Transformation module for an RF amplifier arrangement, RF amplifier arrangement comprising such a transformation module, and arrangement for accelerating particles comprising at least one such RF amplifier arrangement

Abstract

The invention relates to a transformation module (1) for an RF amplifier arrangement, to an RF amplifier arrangement comprising such a transformation module, and to an arrangement for accelerating particles comprising at least one such RF amplifier arrangement, for transforming a first input impedance at a first transformation module terminal (2a) into a second input impedance at a second transformation module terminal (2b). The transformation module (1) can be used in an RF amplifier arrangement. Said RF amplifier arrangement can be used in particular in an arrangement for accelerating charged particles. The transformation module (1) comprises a multi-layered planar substrate (3). An outer conductor (8) is arranged in the substrate (3), said outer conductor having a first and second outer conductor layer (9, 10) which are each in the form of a first or second outer conductor winding. An inner conductor (12) having an inner conductor track (13) that comprises a planar inner conductor winding is formed on an intermediate layer (6). Furthermore, an outer conductor connection arrangement (15) is provided which galvanically connects the first and second outer conductor layers (9, 10) to one another in such a way that an outer conductor casing is formed that predominantly encloses the planar inner conductor winding of the inner conductor track (13) of the inner conductor (12) in an RF-tight manner.
