• FAQ: How can I avoid startup transients when operating the AD8318 in Controller Mode?


    How can I avoid startup transients when operating the AD8318 in Controller Mode?  I am using the AD8318 Log Detector/Controller to control  the output level in an AGC loop.  The control loop consists of a fixed-gain  RF amplifier, an ADL5330 VGA, a…

  • Balun


    I have a doubt about how to use the baluns. I have seen in aplication notes that, in the evaluation boards, if you have a SMA conector (like an input or output to the PCB) it's used the balun to convert the unbalanced input (ANNTENA) to a balanced…

  • AD8317 operation at 10GHz & impedance matching


    I am interested in using the AD8317 log amplifier at 10GHz.  The AD8317 is specified for operation up to 8GHz, but can be used up to 10GHz with a reduced dynamic range.

    The datasheet (page 15) states that implementing an impedance match for frequencies…

    Hi Vincent,

    Thanks for your inquiry.  We have other VGA and Detector products that may work for your application.  A couple of analog devices that may apply are:  ADL5330 analog VGA and a log detector, AD8318 .  Details are available on Analog.com.  See also…

  • ADL5330 and AD8318 AGC circuit

    Hi Experts,

    I used ADL5330 and AD8318 to configure AGC Loop.

    The circuit is same as Fig37 in page16 of ADL5330 spec.

    In CW mode, it works perfect.

    I have a question, if I want to use it in pulse mode.

    Carrier is 500M, the pulse width is 100ms…
