hello guys!
i try to design a diplexer which has 850 mHz low pass and 950 mHz high pass filter behaviour. i use 11th degree chebyshev filters and i get the result but the capacity values are very small like 0.8pF. so i can only simulate, not test my diplexer with real elements. i try to transform these capacities to microstrip lines but in high pass filter part i cant do that. i have min 10 pF capacities so designing with lumped elements is not the best way. any suggestions about that?
thanks..
