Abstract

The present invention relates to a push-pull class E amplifier. Furthermore, the present invention relates to a device comprising such a push-pull amplifier. In the push-pull class E amplifier of the present invention a balun is realized using a multilayer printed circuit board, wherein the balanced terminals and connecting line segments are realized in an upper metal layer, whereas the unbalanced terminal and connecting line segments are realized in at least two lower metal layers.

Description

technical field [0001] The present invention relates to push-pull class E amplifiers. Furthermore, the invention relates to a device comprising such a push-pull solid-state amplifier for industrial, scientific and medical applications such as RF heating, drying and defrosting, and magnetic resonance imaging. Such devices may for example be incorporated in plasma generating devices, laser systems and particle accelerators. Background technique [0002] A push-pull amplifier generally includes a first amplifying unit with a first input terminal and a first output terminal, and a second amplifying unit with a second input terminal and a second output terminal. The first amplifying unit and the second amplifying unit are driven with a phase shift of 180 degrees relative to each other. For this purpose, the signal received at the input of the amplifier is split between the first input and the second input with a phase difference of 180 degrees. Typically, the input of the ampl...
