"Radio unit, and process relating to a radio unit that has a remote amplifier stage connected through a feeder.The present invention relates to an arrangement for controlling and adjusting the output power signals of frequ00b3u00eancia radio sent by a radio unit (100) and the input power of signals fRequ00b3u00eancia radio received by the radio unit.In the case of variations in the amplification / attenuation of transmitter and receiver units, the amplification is compensated in both the transmitter and the receiving party mentioned units.So that the mentioned will remain the same amplification despite these changes in the operation.A signal detector (U ~ det ~) is compared with a reference signal (U ~ ref ~) by means of a difference amplifier (112).With which the difference amplifier (112) generates a difference signal (U ~ and ~).The signal detector (U ~ det ~) is measured by means of a sensor provided in the vicinity of a power antenna (113), and corresponds to the power at which the signals of frequ00b3u00eancia radio are transmitted.The reference signal (U ~ ref ~) corresponds to a desired power signal frequ00b3u00eancia radio transmitted.The difference signal (U ~ and ~) generated by the difference amplifier controls the adjustment of the amplification of a first variable amplifier (109), and a second variable amplifier (110).The aforementioned amplifiers being adapted to amplify radio frequ00b3u00eancia signals are to be transmitted and received, respectively.
