HMC536LP2, HMC629A, HMC802A: internal bias of RF pins

Hello,

I want to use RF switch HMC536 and RF attenuators HMC802, HMC629 for broadband application (LF...C-band). There is a requirement to use appropriate DC blocking capacitor in the datasheet on the RF input/output. Let assume that these parts are cascaded directly. My question is, if the internal DC pre-bias of RF pins is identical or very similar. Thus the DC decoupling capacitors can be omitted, RF pins routed directly and the RF performance is expected to be a better. Or is there any note about the DC voltage on RF pins in the datasheet?
