MPY634: Latency of analog multiplier

srikanth vajrala
Prodigy 50 points
Part Number: MPY634

Can I know what would be the latency of analog multiplier MPY634 ?

Also can I multiply two signals of frequencies around 6GHz ?

Thank you.

    Hi Srikanth,

    the MPY634 has a bandwidth of "only" 10MHz. So, you cannot multiply signals arround 6GHz with the MPY634.

    Hello Srikath,

    The MPY634 is an analog multiplier that utilizes the log-natural relationship between the base-emitter voltage and the collector current to perform multiplication. It doesn't involve any digital circuits and there isn't any latency such as that associated with an analog-to-digital converter. Since its design involves analog circuits consisting of bipolar transistors there is phase shift through the device that increases with frequency. That is normal for any amplifier.

    The MPY634 operation is limited to a few Megahertz maximum frequency; thus, it isn't suitable for 6 GHz applications. It appears you need a device capable of operating at microwave frequencies. It would seem that a diode mixer designed for that frequency range would be able to accomplish the frequency multiplication. I suggest checking the Mini Circuits website.
