Impedence-matched transmitting device having high interference immunity

摘要

According to the present invention, the resistance to interference of a transmitting device, which is particularly embodied as a high frequency transmitter with a transmitter amplifier may be improved, whereby a loss-affected network, for example, in the form of a matching resistance, is coupled to the output of the transmitter amplifier, particularly in the case of low output power of the transmitter amplifier, in order to introduce an impedance-matching at the output of the transmitter amplifier. As such, the reflection of an interference signal coming from a transmitter antenna at the output of the transmitter amplifier can thus be reduced.
