• AD8319对数放大器

    工程师:

            您好!请问这款对数放大器的Response Time参数是指什么意思呢?

    如果我需要放大俩个连续的脉冲信号,这俩个信号如图,这款对数放大器是否可用呢?

    谢谢!

  • RE: RF power Log Detector

    Hi nirbhay100,

    You might consider AD8317 or AD8319. Slope magnitude and polarity are not what you want, but that's easily fixed with an output op amp.

  • FAQ: ADL5902 RMS Detector: Operation at Frequencies greater than 5.8 GHz

    Q.

    The datasheet for the ADL5902 RMS detector shows only limited data above 5.8 GHz but the data sheet front page says it works up to 9 GHz. Can it really operate above 5.8 GHz?

  • RE: New Version ADL5331 test fail

    When a device appears to fail, it looks like its output is very high (about -2.66 dBm instead of -6.37 dBm). Do you have an AGC circiut connected around ADL5331 similar to Figure 19 in the datasheet. Is it possible that this AGC loop is somehow breaking…

  • RE: AGC working at high frequency

    We have a couple of applications notes available on our website, CN-0050 (ADL5330, AD8318) and CN-0082 (ADL5331 and AD8319), that deal with this problem. I'm just using these for reference, as they operate in the 1GHz to 2GHz range, lower than what you…
