Abstract

If an interference voltage is modulated onto the sup- ply voltage of a transceiver unit, all parameters specified in the relevant guidelines must be complied with. One parameter that is particularly affected is the signal/noise ratio of the transmitter (e.g. Staccato TX SIN < 40 dB). This interference is frequently eliminated by means of an expensive filter in the supply voltage. The solution demonstrated here does not require such a fdter.
