ABSTRACT:
A transmission system for digital mobile radio installation mobile terminals includes an attenuator on the input side of the mixer in order to apply to the latter signals at an rms level of only approximately 70 millivolts. The preamplifier is therefore a very high gain amplifier (typically 30 dB) and is followed by a level limiter circuit.
