How annoying. No Idss spec, no DC curves. RF people are like that:
just fiddle with the bias until it works.
Since the abs max range of gate voltage is -8 to -2, it's presumably
destroyed in shipping. Unless they ship it with a battery attached.
Abs max supply voltage is 48, but leakage is tested at 175.
The forward transconductance spec is clearly wrong.
Pitiful. We use phemts in pulsed time-domain applications, and usually
have to test them ourselves to get basic specs. Even the manufacturers
often don't know basic stuff about their parts. A Spice model, or even
basic DC curves, is rare for RF parts.
Don't feel bad, the other day I discovered that we have a tube of power
mosfets 18 amps, 500V out of a batch we order with a different date code
on them that does not pass the 500V break down test, they're good for
only ~250v before they start to break down. These were purchased all at
the same time but this particular tube seems to be older stock.
Not only that, I notice the package, although the same type, looks
like they were made else where on the planet, they don't seem to have
the same exact mold shape. I wonder if I got rebranded or defective parts?
It's not a bug deal, we just put those assigned with a note on them,
they now are test fets, but these fets are not cheap and it's a good
thing I didn't pay for them..
