Rubbish. Varactors are not used for freqency mulitplication. They are
freequenty used in VXCOs for modulating (or otherwise varying) the
oscillator output frequency by means of applying a DC bias voltage
which alters the capacitance of the PN junction.

Your own rubbish, Paul. In truth of fact, varactors are nicely used
for frequency multiplication, just as Tim stated. They also work well
for VCO FM modulation, but users must keep in mind their instantaneous
capacitance-change property and be careful to bias them in appropriate
higher-voltage bias regions, or risk unintended distortion. When used
as multipliers, low-voltage bias with large signals enhances the effect.

You're right. I can't believe I posted that load of nonsense. Maybe
it's a case of "late onset mad cow disease." :-|

OK, you are forgiven, my son. Go and sin no more.

Yes, m'lud. In mitigation I'd like to plead Jack Daniels. :-)

LOL. That'll give you Mad Cow/Bull/sailor/you-name-it disease. Try
Long Island Iced Tea or a quality Rum like Bacardi (no Hangover for
me with that and no Wild Turkey effect ).
