HMC986 DC Block

Hi all,

Looking through the datasheet for this component shows that it is DC coupled.  I am planning on connecting several of these back to back.  Will I need to worry about having a DC blocking capacitor in between each switch or is this not necessary?

There will not be any DC MMIC bias anywhere on the RF line. 

Another concern is that I received this email from when I queried the HMC986:

"HMC986 is not recommended for new design."

Could someone please elaborate as to why this is?

Any help would be greatly appreciated.
