Why is a capcitor needed at output of Pi Resistive attenuator if the input to attenuator is pure AC signal with Zero DC content. The attenuator is designed to work from 40MHz to 1GHz.
My circuit has an LNA followed by Attenuator and a tuner IC. the LNa output has DC blocking caps. so is it needed to add one more DC blocking cap just after attenuator. the input to LNA is 40MHz to 1GHz without any other frequency components
