LMX2595: Output power dynamic range / resolution of LMX2595

Part Number: LMX2595

Hello,

The output power of the LMX2595 can be varied using the OUTA_PWR and OUTB_PWR registers (R44, R45). The question is: By how much?

Say I'm using the 50 ohm resistor pull-up on the outputs and operating at 15 GHz. Roughly what is the power range (and resolution) that can be achieved by changing the OUTA/OUTB_PWR registers. The data sheet makes clear that it is not a linear dependency but I could not find any mention of the dynamic range or resolution.

Thank you,

Tony

  • Hi Tony,

    The rev C of datasheet added this plot in Figure 26. Note that this is NORMALIZED power. You may refer to Figure 23 and 25 for absolute power.

    The rev C is available on web now. If you cannot see it, you may need to clean the cache of your browser.
