        Hi,

        I am based in UK, I am trying to take RF career advice consultation.
        The timing is very odd for me, is there any chance you can change the time that suits BST please.

        I am trying to use Coupon, it is not working.

        Many thanks

        in example 2.2.9 how did you get |Vs|**2 = 16? Assuming Vs is an rms value then would Vs not be 8/sqrt(2)? what am I missing and the max power be equal to 2 wats? Thx

        How do we produce +1 and -1 voltages?

        • Admin bar avatar
          Ahsan Ghoncheh
          July 16, 2018

          you can use analog comparator with VDD=+1 and VSS=-1 then reference voltage of vref=0.5

          when your input is 0 and less than 0.5 comparator output will become -1 and when it is 1 which is higher than 0.5, output will be +1.

        Why do we need the 90 degrees part of the diagram?

          You are correct . I checked and the file had been removed due to our AWS server update. The issue is resolved now and you can download it.

        From where are de-generating frequencies generated in amplifier designed at 5GHz. Are these frequencies coming from power supply or due to non-linearity in transistor.
