Then that's pretty dandy then, 3000 I thought was in the realm only metglas can get you. Life truly is far more than the wikipedia page lets on. Pic related, it shows both for one stat, then one each for the other two. I can understand that it's convention but surely it would be helpful to share units for intuition's sake.

I'll just write down mixer stats here because I'm lazy:
SA602:
~$0.6 ea (ali)
f_max = 200MHz
Oscillator driver built in

SA612:
~$0.7 ea (ali)
Same other stats

Looks like the NE567 could be used as an IR remote decoder among other things, though with a little more work either of the above would also work fine. 500kHz maximum. Though when receiving a, say 40kHz signal into a mixer, I assume you'd want an oscillator frequency not at 40kHz but maybe around 39.95kHz, so you could feed the output into a low-pass filter, then an amplifier and rectifier if you needed a square wave. If you set the receiving frequency to exactly the same as the transmitter, if the phases matched up wrong you'd get no signal out at all. The 567 on the other hand explicitly states that it directly turns CW into DC pulses. IR remotes are on my to-do list, but for now I'll buy 5 or 10 602/612s since they look damn handy to have around.
