Frequently Asked Questions about Multipliers

Quick Link Reference

Question: Do you make space-level multipliers?

 Answer: We have manufactured many standard multipliers for space projects. Typically JANTXV level diodes are up-screened to space level, and additional testing and source inspections performed on the final assemblies. View a list of space projects VMI has contributed to.

Question: Will a multiplier work at an operating frequency of 60Hz?

 Answer: No. Most multipliers work best between 25KHz and 150KHz. There are exceptions to the rule, but generally the absolute minimum operating frequency is 10KHz.

Operating frequency directly impacts

  • Ripple voltage (the higher the operating frequency, the lower the ripple voltage)
  • Regulation voltage (the higher the operating frequency, the less drop in output voltage at load)

Question: How does temperature effect the output of the MVM302P08 hybrid multiplier?

 Answer: Keeping all things constant, the output voltage decreases as the temperature increases. There is a significant drop-off at temperatures higher than 150C. Other factors effecting output voltage include load current and operating frequency.

Question: Do the MVM series multipliers come in a negative Vout version?

 Answer: The MVM series can be used to generate either a positive or negative output voltage.

  • To get a negative output voltage from the MVM type series, connect your input signal to V2. The HV output will be V1, and the output voltage will be negative.
