Hi,
I am looking for cheap solution multiplication two low frequency (up to 10 Mhz) low voltage (up to 3V) signals.
Could you recommend me something
Thank you
 

Hi,

Frequency multiplier: --> PLL
Analog signal multiplier: --> something like good old AD534?

AD534 is good enough but price is tens dollar is too expensive...May be exist any cheap solution?
 

According to catalog distributor part search, AD633 is the cheapest available type.
 

Perhaps the old LM1596 could be adapted to your needs.
Page 5 shows it being used as a frequency doubler and I would think you could separate the two inputs to multiply two different frequencies.

Good analog multipliers inherently require fancy technology to manufacture. Maybe if you explain your application we can help find an alternative.
