In the sixties/early-seventies, I remember there were a number of circuits published for things like VHF or UHF frequency-multipliers/mixers/modulators that used Hot Carrier diodes [the Hewlett-Packard HP2800 series were often specified].

They were not cheap!

You never hear of them these days, and I was wondering what became of the technology?
