Looks exactly like the Amazon part that's 44 cents.

That's a good price for 3.5 mm connectors. They are
precision connectors that are OK to 35 GHz, unlike the
Amazon SMA shit that maxes out in X band if you are lucky.

SMA connectors with their loose mechanical specs can
easily kill 3.5 mm connectors. The center conductor in
3.5 mm connectors is often held by just 1 or 2 mica
pieces & air. You may get away with mating them to SMA
but this is abuse and removes the better frequency behaviour.

I have some 3.5mm connectors were you can see through
in the long direction. The mica disks even have 6
boreholes around the center conductor to limit their
influence on the local eps-r. We don't want no low pass.

The edge-launch cheapies look good with a 20 GHz TDR, if you get the
PCB layout right.

Pasternack pricing has always been insane.

My (limited) experience with industrial trade shows is that connector companies send their best salespeople. For whatever reason other
companies with much more interesting products on paper sometimes seem to
send whomever is available.

CES is sort of like that lately too, like who have we got around to go
to this thing? Hey you're not doing anything why don't you go. There
will only be thousands of potential customers and influencers with
hundreds of thousands of followers there with a plausible advertising
reach of millions. Just sit around on your phone and ignore them, it's
cool.
