  • Can I/Q differential output of AD8347 connected to AD9231 directly?

    Hi,

    I have a new design,that I will use AD8347 and AD9231.I got two question about the circuit.

    1.Can the BB amplifier of AD8347 drive the AD9231 directly without off-chip AMP?(No input buffer in AD9231)

    2.The differential input of AD9231 is 2V p-p…

  • AD9235 with AD8132(AD8138)

     

    Hi

    Could you give me any advice as below?

    I have been designing PCB using AD9235 and AD8132.

    I have designed AD8132 using input signal impedance matching as 50ohms to get differential output.

    My question is to confirm the connection between…

  • FAQ: Can AD8346 be operated at frequencies below 800 MHz?

    Question: FAQ: Can AD8346 be operated at frequencies below 800 MHz?

    Answer: For starters, there is only one good reason to try and use the AD8346 at frequencies below its specified 800 MHz minimum. And that reason is the fact that the device has…

  • RE: ADL5385 Output Level and LO Drive

    It is good to hear that the output power of ADL5385 is now normal. In terms of EVM, please check LO Leakge level which is also related to EVM performance. If possible, you can get better EVM by nulling LO Leakage level. Refer attached file for correcting…

  • RE: I and Q not 90-degrees apart (AD9854)

    Hi Matthias,

    Thanks for your answer, it was very detailed and most helpful. I'd come to the same conclusiion that I and Q outputs are fixed at 90-deg and no trimming is possible although I was hoping I'd missed something in the DDS datasheet. It does…

  • RE: How to improve AD8346 performance considering its SSB phase noise

    The phase noise at the output of and IQ modulator comes mainly from the Local Oscillator input and from the LO path inside the IQ Modulator. As you can see below, the phase noise of local oscillator signal spreads the desired signal. So if you want to…

  • FAQ: When I use the Auxiliary DACs to compensate for IQ Mod LO Leakage, what resistor tolerance should I use?

    Q.

    I want to use the Auxiliary DACs of the AD9779A to compensate away the LO Leakage of an IQ Modulator. I am using the recommended schematic from the data sheet of the ADL5370/1/2/3/4 family of IQ Modulators. What resistor tolerance should I choose…
