Hi Sir,

    In ADRF6510 datasheet,  it is used for baseband I/Q receivers and ADC Drivers.

    But I want to use it between DAC and Modulator to be TX smoothing Filter.
    What should I have to pay attention to in the design?
    Is there any reference circuits about ADRF6510 used be TX smoothing Filter?
    Another question is ADRF6510 has variable gain amplifier(VGA) , but datasheet does not
    have the information about the VGA response time.
    Is there any testing results about the response time?
