    Hello Archie,

    Based on the data sheet (p. 6), there is no minimum value of output power that will affect the part, as shown below; therefore, you should be able to configure the part as low as possible.

    Hope this helps!

    Good Luck,

    Andrea

    Hello Andrea,

    Yes, that helps.

    We want to know how low we can drive the output power to. Customer want it to go down to -10dBm. They set the OUTx_PWR to 15 or even 0, was getting -4dBm at 15GHz. If set it to 31, it gets 0dBm. Is there a setting that we can get to -10dBm?

    Please advise. Thank you.

    Regards,
    Archie A.

    Hi Archie,

    If -4dBm is what the customer got at setting of 0, then this is the lowest output power we can configure. A 6dB pad after the synthesizer is a good idea to bring the power down.
