Yttrium iron garnet tuned oscillators were around back then, but their
2GHz to 8GHz range was too high for me to count with the integrated
circuits around then - we had to go the Gigabit Logic's GaAs parts to
get to 800MHz, and that became the unique selling point of the system.

YIG oscillators were quite the thing back in the day, but I'm guessing
they've been completely superseded by now to get to ever higher
frequencies. Seems we've gone from -
This misses Jan Panteltje's thread "Small magnetic tunable filter for 6G and beyond" which is about Yig being used today.
R/C to L/C to Xtal to YIG since about 1900. Did I miss any development(s)
out pre-YIG?
Tuning forks, SAWs, BAWs, mechanical ceramic resonators, dielectric
ceramic resonators, coaxial ceramic resonators, sapphire, cavities,
atomic things.
As usual, John Larkin hasn't noticed that most of his list can't be rapidly tuned to a different frequency.
