QPC6713 reciprocality and DC block

Hi,

I’m using two QPC6713 in series. Is it recommend to have DC block capacitor between two attenuator?

Can I use RFIN as output and RFOUT as input without performance change?

Input from Qorvo Product Applications: There is no DC blocking capacitor required between two QPC6713 cascaded. The RFIN and RFOUT are with different power handling capabilities. Follow datasheet specifications, the RFIN and RFOUT are swappable. High power hot switching is not guaranteed.
