Abstract:
1. A receiver for receiving radio frequency signals and comprising: a first stage for amplifying and tuning radio frequency signals and for generating intermediate frequency signals; a first gain controller for controlling a gain of the first stage; a second stage for amplifying and demodulating the intermediate frequency signals; and a second gain controller for controlling a gain of the second stage; which first and second gain controllers control the gains independently from each other with the first gain controller to control the gain of the first stage based on a modulated intermediate frequency signal at an input of the first gain controller, and the second gain controller to control the gain of the second stage based on a demodulated intermediate frequency signal at an input of the second gain controller, wherein both gain controllers are adjusted at the same reference level for controlling the gains in relation to this reference level.
