A single diode alone can not multiply frequency - it can only divide frequency.
Two diodes in full wave split mode, or 4 diodes in full wave bridge mode, will seem to multiply frequency, due to the fact that alternating polarities of the AC wave will be flipped and superimposed on the resulting DC. It should be noted, however, that this is not true multiplication, because the result is not sinusoidal.
It is possible to filter the output and make it look sinusoidal, but that filter design will be very complex.
*************************************************************
Yes, a diode can be used as a frequency multiplier.
A diode is a non-linear device, and any signal passed through a non-linear device or circuit will result in harmonics being generated. If the signal passing through the diode is not a sine wave then harmonics of all the other frequencies present at the input will also have harmonics generated. There will also be the sums and differences between all the reultant frequencies.
That is why a diode is used as a "detector" in an a.m. receiver. Another name for a detector is a mixer, the other name for which is a multiplier.
The varactor diode is used in frequency tuning applications. Its effective capacitance is a function of the reverse bias voltage across it.
oa79 is frequency diode... it pass only the bit of frequency..

If the reverse recovery time of the diode is too long for the operating frequency, the diode will never turn off.

System bus frequency and multiplier
The frequency response is nothing but how fast the diode is responding for the given amount of voltage from source. The resulting waveform will be in the frequency domain representation system.
Gunn Diodes are used in high frequency electronics. The advantages are increased efficiency and improved temperature stability while a disadvantage is the Gunn Diode can get burned out.
UHF and microwave
line Frequency diode have very low forward bias drops but their recovery characteristic(time) is very long. Their softness factor is low.
You end up with the advertised/effective CPU speed, such as 2.8GHz.
