In my circuit, I have cascaded HMC994 amplifier, blocking capacitor, 0dB gain equalizer, blocking capacitor, HMC994 amplifier, blocking capacitor, and 5dB gain equalizer in series. As per design calculation cascaded gain should be (14 - 0 + 14 - 5) 23dB or at least 18dB should be come. But practically its come as 13 dB only. Can any one explain why is the spec as per datasheet not met ? Or is there any conditions applicable while connecting the amplifier with equalizer? Kindly provide the solution for my Query. Thanks in advance.
