Menlo Micro is making some grand claims for their power and RF relays.
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.
