    Hi,

    Could you please refer me to info sources that discuss Gain Control?
    I didn't manage to find much info on it in web.

    This is part of my studies of RF Power Amplifiers.

    Thanks.

    Hello,

    I have moved it to the "radio and communications" forum, as it is RF related.
    You can perform RF attenuation with a PIN diode attenuator.

    Hi Bertus,
    I'm not sure how RF attenuation related to Gain Control.

    Currently, I'm looking for info for learning what is Gain Control and its basics.

    There are a couple of documents in this thread. This will help with general concepts, but RF design is a more difficult aspect of what you are asking.

    Maybe you meant AGC, or Automatic Gain Control? That might be a feedback system that attempts to maintain a constant RF power level, at some point in a system.
