HMC544A: DC blocks at ports RFC, RF1 and RF2

Hi,

 

I am working on a high speed data aquistion system. The low power RF signal of interest is DC coupled and therefore I was thinking of using the HMC544A as a switch. The datasheet looked promising (DC - 4GHz) until I have found the section that DC blocks are required. Using DC block capacitors is not an option. Would it be worth a try to leave out the DC blocks?

 

Thanks and best regards,

Gerald
