    Well, that is odd. How would you explain that we use the ICS40730 in many devices with great sucess and in your setup the output is not clean? I am not sure what you mean with two outputs? The ICS 40730 has only...

    Hi Holger, give this a try also, its a very nice filter designer and also plots the response and gives you the coefficients. Also helpful is the possibility to test the filters with different accuracies of your...

    Hi Frank, I have no experience with PIN diode switching, but they are said to have low resistance against IM3, which means that high signal levels can seriously distort your reception. Could be that you can improve...
