• FAQ: AD8309 Limiter impedance

    Q.

    What is the impedance of the limiter in the AD8309?

    -------------------------------------------------------------------------------------------

    A.

    The limiter used in the AD8309 is an open collector circuit. The impedance is determined by the value…

  • FAQ: AD8309 Limiter output swing

    Q.

    As per the AD8309 data sheet the limited output VLIM = VS – 400 mV × RLOAD/RLIM (data sheet page no:17). In our design we have RLOAD=499 ohms & RLIM = 402 ohms. For this we are getting 250 mV output in each pin. It didn't match with the given relation…

  • AD8309: Limiter Amplifier

    Could you give me more information on the Limiter Amplifier?

     

    The AD8309 can provide a large voltage gain combined with
    progressivecompression, through which an IF signal of high dynamic range is
    converted into a square-wave (that is, hard limited…

  • AD8309: Overshoot atfer rise time

    I use a AD8309 in RSSI mode.
    There is an overshoot after the rise time: Why ?

     

    The overshoot you have observed is basically the nature of the AD8309 output
    stage, it takes a few moments to settle. There are one of two things to deal
  • Is there any AD8309 spice model or how to simulate AD8309?

    I need to simulate AD8309,but ADI doesn't offer the spice model, is there any way to simulate AD8309

    Thanks!

  • RE: AD8309对数放大器限幅输出振荡

    您好,感谢对ADI产品的支持。

    AD8309是能够对5M到500M的信号进行检波输出的。输入功率范围以及响应时间请参考手册的参数表。

    您也可以将您的电路以及输入输出波形发出来帮您进一步分析一下。

  • AD8309 to Control ADL5530 RF Gain Stage

    Good morning-

    I'm planning to use an AD8309 as an IF limiter for an all-analog FM receiver design. While I realize that FM doesn't typically call for any type of AGC, I would like to use the VLOG/RSSI output to control the gain of an ADL5530 in the RF…
