I kind of regretted tossing the GBL data book in a big cleanup, but I found a scan online.
That took all night to load, so I posted a copy:
I thought GBL died, but they were actually merged into TriQuint, which was a Tektronix spinoff. The logic parts are of course gone.
Their logic was based on depletion-mode gaasfets, so was expensive and hugely power-hoggy. Modern SiGe is faster and uses a fraction of the power, like EclipsPlus.
There are now some exotic SiGe gates with 30 GHz rates, 10 ps edges, for, like, $600 per gate.
