  • Hi Snow8321,

                            How are you measuring the power level? power meters usually measure the average power not the peak power. Are you accounting for the duty cycle in your measurement?

    It is also possible your board may not have adequate heat transfer to remove the heat from The ADL5605.

  • hi jim

    thanks for your detail explanation. the outpower was measured by signal analyser. cannot get clear peak power. I also found the power of 11b is much higher than11g signal. i have shared the comments  from you to the designer.
