That's an unabashed advert, of course, but I agree that
Pickering makes nice reed relays. I've used them and I'm
happy.

Reeds are expensive unreliable power hogs.

A cheap DPDT FTR-B3GA4.5Z-B10 is good at 3 GHz. There's a latching
version too.

Just don't water wash.

Yea, I have some of these:
http://panteltje.com/pub/SMA_relays_IXIMG_0872.JPG
18 GHz 300 W
https://www.ebay.com/itm/133870232177 $38
Did not pay that, mine came from the used supercooler for cellphone tower filter I bought.
Did not need the relays for cooling...
Have several read relays too,,

Those types are fabulous in test sets and such, but not on PC boards.

I recently used a bunch of ADRF5024 IC RF switches. 44 GHz. Expensive.
Work great.

https://www.dropbox.com/s/0pjtpru3fgk9fcl/28S502B.pdf?dl=0

It switches between signals mid-waveform, in around 6 ns.

>Did not need the relays for cooling...

I wonder what that Pickering thing costs.
