ABSTRACT:
An amplifier assembly and also a receiver including such an amplifier assembly is disclosed, wherein the amplifier includes a programming input for setting the gain thereof. The signal level at the output of the amplifier is compared with a reference level and a counter is incremented in a step-by-step fashion such that the gain in the amplifier is reduced for as long as the output level lies above the reference level. The amplifier assembly enables frequency-dependent received field strength fluctuations that occur in frequency hopping methods to be corrected in a manner dependent on the conditions in the current time slot. The assembly is also suitable for modulation methods that use a modulation with phase and amplitude variation.
