Can anyone here solve a "disscusion" in another newsgroup, does RF ever
stand for 'rectified frequency' or is it always 'radio frequency'?

I've only ever known RF to mean radio frequency over many years of dealing
with comms.

Always Radio Frequency.

"rectified frequency" makes no sense because rectified AC is DC which does
not have a frequency.

The term does get used to describe harmonic components generated from
using various rectification schemes. Very minor use though - google
comes up with a handful of hits, and none abbreviated to RF.

Be interested to know what this other newsgroup (web forum?) is - can't
find that post.

Surely 'rectified frequency' is DC? Although with some ripple on it unless
smoothed?

Always Radio Frequency.

Only if it is 'smoothed'. Otherwise it is a very bumpy/spikey waveform.

Blame the heat streaming into this room from that fiery thing in the sky
(Can we get rid of that? Pelt it with ice cubes?). Yup I did see that
non-rectifier reference and forgot it might have some relevance here...

Me off to creep under a nice cold stone....

r.f. means "radio freqency", all electomagnetic waves up to infra red
(but usually between about 100Khz and 15Ghz).

Equipment for rf freqencies has to be treated as transmission lines and
antennas, since device size is similar to actual wavelengths.

microwave devices, above about 2 Ghz, start to look like "plumbing"

Not if it's the output of a diode detector for an AM transmission it's not . . .
oh how quickly we forget :-D.
