When I am cascading stages with at 75MHz
AD8367 + AD8367 +MMIC Amp + BPF + Power Splitter
40 + 40 + 16 -12 -4 = 80dB
Theoretically I am supposed to get 80dB when cascading above stages, but I am getting nearly 60dB only instead of 80dB. When tested individual stages all of them are giving gain/loss as per the above figures. Can any one suggest what to be done to get the full gain.
