• ADL5390

    Recently I’ve been using ADL5390. I can’t found Application manual about this chip. Is it convernient for you to send a file to me.

  • DAC to use with ADL5390

    We are updating an IQ Modulator design that currently uses an AD9777 DAC to drive the I and Q inputs of an ADL5390 as per the ADL5390 data sheet (figure 32).

    The AD9777 DAC is now listed as 'Not Recommended for New Designs'

    What DAC should we…

  • RE: searching for a device that can transmit RF signals with desired phase angles

    Take a look at HMC631 and ADL5390 which are vector modulators (allows adjustment of gain and phase).

  • Shorted out ADL5390-EVAL

    I accidentally shorted out the ground and +5 V supplies for the ADL5390-EVAL board. The result was a small spark, and now they are permanently shorted. I was hoping to find an obvious coupling capacitor that might have been busted, or a resistor that…

  • RE: Single-Ended Operation for ADL5390

    Hi Alex.

    the ADL5390 is an RF/IF Vector Multiplier. Being such, the component needs a Vector input and will deliver a Vector output. As you are fully aware, this vector needs both an I and a Q component. The ADL5390 has a useful feature where you can…

  • ADL5390 Low-End Input Frequency Limit

    Question: What limits the low end frequency limit of 20 MHz on ADL5390? Is it internal ac-coupling?


    Answer:  Yes, there is AC coupling on the output buffers.

  • ADL5390 Minimum Operating Frequency?


    Just wondering if anyone knew if the ADL5390 could be used any lower than the 20 MHz specified in the datasheet.  I saw another product reference that specified 10 MHz as the lowest frequency for the part.  I was wondering if the freq range specified…

  • ADL5390 ETC1-1-13


    One of my customers is designing the PCB for ADL5390.

    One of the peripheral part, ETC1-1-13 seemed to be changed the pin-assignment.


    Can they put ETC1-1-13 as attached file?


  • RE: Large unexpected modulation in ADL5390-EVAL

    Are you using the main output of your VCO (ZOS 200+)?  This has a +10 dBm output. You are compressing the ADL5390 for sure and mostly likely the AD8368 (what is the gain of the AD8368?).

    Max input/output for the ADL5390:     7/11 dBm  (1.42/2.24 Vpp) @ 140…
