Req: need help about analog switch

Hi all.
I have a problem on working with analog switchs.
has anyone any experience about working with mini-circuits analog switchs?
my problem is that beetweem RF-out and ground is a very low impedance about 5 ohms.
i will happy if you can help me.

I had no problems in using Mini-Circuits switches (several models). Are you sure that you don't have an error at PCB or broken component?

How about the circuit after output?Does that shortcircuit?

Maybe you do not mount the switch on PCB correctly.
