• RE: What is the difference b/w AD8306ARZ & AD8309ARUZ Log amplifiers

    Hi Sugumar,

    There are some slight differences between the AD8306 and the AD8309.  One of which is the frequency response of the limiter output: 585 MHz for the AD8306 vs.  875 MHz for the AD8309.  Note we test to 500 MHz for the AD8309 and only to 400 MHz…

  • RE: Log/Limiting amp use

    The ADL5304's max input current is 10 mA (please see figure 10mA), so you will only get 80 dB from the ADL5304. 

    For the AD8306/09, near DC frequency should be able to be obtained by having large input AC coupling caps.  Please see Table 3 on page…

  • RE: Replacement for SL532 low phase shift limiter

    Take a look at the following parts on Analog.com:

    • AD640
    • AD641 (similar design to AD640 but faster)
    • AD606
    • AD8309
    • AD8306 (modified version of AD8309 with military/aerospace version)

    The most versatile device (highest frequency range, highest…

  • RE: Which logaritmic detector has best linearity?

    HMC601LP4 has better detector linearity error response than AD8306. However, it may not be met your 0.1dB error requirement.

    Following the link to the device’s data sheet. The top 2 graphs on page 12-12 show the responses at 100MHz and 500MHz:  http:…

  • AD8302 Accuracy

    Hello Analog,

    I have two sine wave signals, say A and B. Each has identical frequency (maybe out of phase) anywhere between 5-100MHz and amplitude over 60dB range (1:1000).

    However, at any specific time, the maximum difference in amplitude between signal…

  • RE: AD8307 - Detection of short burst with preceding filter delay

    It might not even respond at that low of frequency (it looks to be near 30 Hz).  The AD8307 will only have a couple of cycles to respond to in the time periods you are quoting above. What is your frequency(s) of operation?  I may be able to measure the…

  • RE: Help with AD8302

    You should probably attenuate the reference signal a bit, down to 0.5 Vpp range.

    1MHz is a little low in frequency.  Take a look at the attached app note for low frequency operation of detectors.

  • RE: AD8302 cap changes

    Please take a look at the attached app note.  Page 13 is section on the AD8302.
