• RE: AD8361 Inaccurate

    Dear Bruce_H

    I designed the circuit according to datasheet. The input end is connected with 100nF capacitor in series and 75 Ω resistor in parallel. According to the manual, the input impedance is close to 50 Ω, but the input impedance I actually measured…

  • RE: AD8361 output drive

    Hello Karol,

    I'm not sure why the apparent gap in output drive capability. Driving 5V across 10k ohm load will require 0.5mA, so it's possible that the remaining 2.5mA can be used to charge capacitive loads (Ic= C*dV/dt).   -Bruce H. 

  • AD8361 application

    I first want to summarize my need. I have a prototype portable instrument and need to produce more units. The unit has an 18 MHz source and applies a stimulus voltage to an unknown and a signal returns. I only need to measure the amplitude of this pure…
  • Regarding Ad8361

    Hi All,

    I have a prototype with me where in i need to measure the RF power and Freq=20Mhz.

    I have used Ad8361 with 1.5nf Cc and can i feed V peak-Peak voltage at RFin or do i need to feed the rms value at the input of AD8361.

    Will the output of AD8361…

  • AD8361 failures

    I have a puzzling situation with the AD8361ART (the 6 pin version).  I had 3 in a row fail as nearly instantly as I can tell - that is as soon as I power up the board, the AD8361 is dead.  The failure is exhibited by the Vrms pin going to +3.2V even with…

  • AD8361 and LTC5582

    Question from a customer...

    I am looking at two power detectors to assess performance? AD8361 and LTC5582. My input freq range is 950 to 2150MHz and application is to monitor high level interference when present at receiver input to avoid ADC over load…

  • Question for AD8361

    Dear Sir/Madam,

    I have a question for AD8361.

    As for your "Output Intercept" on page-3 data sheet,

    These ratings are guaranteed when no-signal also, correct?

    Does it means same as offset voltage?

    Thanks, Kaos

  • AD8361 Output Offset Voltage

    Question:  I have an evaluation board for AD8361.  With the board powered and no RF input connected the output is greater than 150 mV eventhough the specifications call out a maximum Output Intercept of 150mV.  Is there something wrong with his part since…
