• AD8364

    I want to measure differential power at different frequencies. I want to use AD8364 detector .How do i calculate power for frequencies whose corresponding slopes are not given in the datasheet?

  • AD8364

    Hi,

    We are using the AD8364 in the band 2.110 to 2.155GHz.

    We are getting a relatively large frequency dependent power measurement error.

    For example, if the device is calibrated (intercept and slope) at 2132.5MHz and we inject a signal at 2112.5MHz…

  • AD8364 evaluation board

    The RMS Power Detector AD8364 evaluation board AD8364-EVAL-2140 is described for use at 2140 MHz.  To measure 2.4 GHz, will I need to replace the Murata LDB212G1020C-00 balun with the Murata LDB212G4020C-00 myself? Is it possible to make this changes directly…

  • AD8364 input power levels

    In the datasheet  for AD8364 , there are different max and min input levels for different frequencies .

    Are these experimental  limits used for calliberation of slope and intercept?

    Can i use input power exceeding that given in the datasheet for the frequencies…

  • AD8364 Input transformer question

    Table 4 in the data sheet lists other "baluns" that were used during part characterization.  In looking at the second selection (Mini-Circuits JTX-4-10T), it doesn't appear to be a classic balun, more of an RF transformer.  Is this correct…

  • AD8364 Operation at 2.7 GHz

    Question: AD8364 is specified to operate up to 2.7 GHz but the datasheet only shows data at 2.5 GHz. Do you have any data showing performance up to 2.7 GHz.

    Answer: The attached plots show sweeps of Channel A and Channel B at 2.7 GHz.  In the first…

  • AD8364 and AD8362 TruPwr Detectors

    I am looking for a device that outputs the instantaneous power of a 1MHz ultrasonic sonar echo as a means of estimating range from the change in the sonar transducer output power.  The input signal will be a modulated 1MHz sinusoid having a maximum peak…

  • AD8364 evaluation board eval-z

    I have purchased an Ad8364 eval-z evaluation kit. It has provisions for header but the holes are filled with soldering metal(According to me).

    What precautions should i take to while soldering the connectors since it is multilayer board or Do i have…

  • AD8364 calibrate the detector for return loss/VSWR?

    I'm looking to calibrate the AD8364 power detector using a method similar to what is described in the below conversation, but because I don’t have ADC access to OUTP and OUTN in the Alpha prototype
    design, I was simply going to use OUTB and OUTA measurements…

  • Output Linearization of AD8364 for RF Power Measurement

    I'm developing a microprocessor monitored and controlled RFPA that outputs +30dBm to +61dBm CW between 10MHz to 15MHz. To accomplish this, I need to be able to measure RMS power with at least 40dBm of dynamic range; preferably 50dBm.

    There are a number…
