They appear to be electrostatic MEMS relays. Lots of people have tried
that in the past couple of decades, but the parts haven't been
reliable.

On-State Insertion Loss is only stated at 6Ghz. I'd be interested to
know what it is closer to the top end. A graph would be better,
though.

All the parts can only cold switch. That would seem to be a problem, >especially for the power parts. How do you cold switch a circuit
breaker?
The two killers of MEMS relays have always been contacts frying and
contacts sticking.

Holy crap, I didn't spot that! Big downer.
