• ADF4360 Phase Noise Spec

    Hi, I am currently using the ADF4360-9 to generate an LO ref in the range 146-152 MHz. My phase noise requirements are quite strict so have ended up running the VCO at double this and using the Divout f/2 output to get a slight improvement in noise performance…

  • External reference connection to AD7380-4, AD7381-4, AD7389-4

    Hi Support Team,

    I'd like to use AD7380-4, AD7381-4, or AD7389-4 with a 3 V external reference. Please answer a couple of questions:

    1. The datasheets of AD7380-4, AD7381-4 tell that an external reference can be connected to the REFIO pin (pin #17…

  • ADF4360-9 VCO process variation

    Hello,

    I am using ADF4360-9  as a transmitter with FM modulator on the VCO (Vtune).

    To ensure reliable performances on the modulation, I would like to avoid switching VCO band when varying across the temperature range.

    I have already reduced the inductor…

  • EV-ADF4360-9EB1Z

    Hello

    I have started using EV-ADF4360-9EB1Z through GUI provided with the evaluation board. As default the "RF Output Frequency" is set as 360 MHz. As per datasheet, primary output range is 64 to 400MHz. When i enter 200 as "RF Output Frequency…

  • ADF4360-0 : Frefin below 10MHz ?

    hy,

    in the data sheet of the ADF4360-0 frefin minimum is mentioned with 10MHz with an advice to couple below 10MHz via DC. I try to use 2MHz TTL-Signal to frefin with the result of large jitter on the R-Out monitored on MUXOut and no lock of the PLL. 

  • On EVAL-CN0313 there are three different circuits that offer various protection levels for IEC61000-4-2 ESD, IEC61000-4-4 EFT and IEC61000-4-5 Surge. Why is there different protection circuitry used for Surge Level 4 compared ESD/EFT level 4?

    The EVAL-CN0313SDPZ is a certified EMC Compliant RS-485 Interface Design Tool. 

    The main reason for the different protection circuitry is related to the difference in energy levels associated with each of the transient waveforms. According to the IEC61000…

  • Ev-ADF4360-1EB1Z L1,L2

    I bought the Ev-ADF4360-1EB1Z. When I look at the board, L1, L2, R25 and R26 are all not mounted.
    Is this correct?

  • RE: 4*4 Tx/Rx Beamformer

    External LO has a divide by 2 inside. This divide by 2 is random, and it's randomness is determined by the LO input power. (if LO goes away, and comes back, then the phase of the divide by 2 is random). This randomness also depends on power up cycles…
