Abstract
An apparatus for coding a signal by means of amplitude shift keying comprises a class E amplifier including a switching transistor, to whose gate is supplied a voltage having an operating frequency for operating the class E amplifier. For achieving an amplitude shift keying in the output signal of the class E amplifier, a circuit for switching the operating frequency of the voltage supplied to the gate of the switching transistor, or the resonance frequency of the class E amplifier, between a first value and a second value is provided and in order to switch a deviation degree between the operating frequency and the resonance frequency between a first value and a second value.

An apparatus for coding a signal by means of amplitude shift keying, comprising a class E amplifier including:
- a switching transistor, to whose gate a voltage is supplied with an operating frequency for operating the class E amplifier;
- and
- a circuit for switching the operating frequency of the voltage supplied to said gate of said switching transistor, or the resonance frequency, of said class E amplifier between the first value and the second value, in order to switch a deviation degree between the operating frequency and the resonance frequency between a first value and a second value.
A method for coding a signal by amplitude shift keying, comprising steps of:
- operating the gate of a switching transistor of a class E amplifier having at least one operating frequency FT, wherein the class E amplifier has at least one resonance frequency FR;
- and
- switching in the clock rate of a data communication between a first deviation degree and a second deviation degree between the operating frequency FT and the resonance frequency FR, wherein:
- said switching of the deviation degree can occur by switching between two different operating frequencies, and/or by switching between two different resonance frequencies, of the class E amplifier.
A primary side plug connector element of a plug connector coupling, which comprises:
- a primary side plug connector element and a secondary side plug connector element, wherein:
- said primary side plug connector element includes an inductive transformer for transferring data and energy to the secondary side plug connector element;
