• ADL5380 Image rejection at higher IF

    Hi, 

    Do you perhaps have any data on image rejection for higher IF frequencies? Specifically around 250 MHz, while the RF frequency is 5250 - 5750 MHz. If you have data for both high-side and low-side LO that would be great. 

    Thanks

  • RE: ADL5380

    Hi David,

    I need your help.

    I am testing the new Eval board of ADL 5380 .

    I have done all the necessary changes  told by you for the operating frequency 5.81Ghz at Lo and Rf like

    1. Removed R13 to R16

    2. Populated R2 to R5 with 0 ohm

    3. Populated R6 and…

  • Single ended operation in ADL5380 for DC output

    We have the eval board of ADL5380. We desire to operate it in a single-ended mode. As suggested in the datasheet the RF and LO input already has a 100pf capacitor connected to one port and ground on the eval board for single-ended mode.  According to the…

  • FAQ: Understanding ADL5380 IQ Demodulator EVM Performance Plots

    Figure 83 and Figure 84 of the ADL5380 datasheet show EVM curves for demodulated WiMAX and WCDMA respectively.
     
     

    Q.

    Why is there an EVM difference between the 10MHz BW upstream WiMAX signal at 2.6GHz and a WCDMA signal at 1900MHz? The difference…

    Re: ADL5380 DSB NF Measurement by Qui

    Hello HJ,

    A standard agilent NF meter (like the N8974A) by its nature is measuring DSB.  In the case of the ADL5380 the DSB number of one channel (I or Q) is measured and reported.  Because the ADL5380 is an I/Q demod…

  • ADL5380 Insertion Loss Issue in Lower Frequencies (400MHz-2GHz)

    Good Evening Sir/Madam,

    We bought ADL5380 EVM  from Analog Devices.

    Practical Observations

    1. As per datasheet, this EVM provides 7dB insertion loss at 900MHz, but we observed that ADL5380 is providing 30dB insertion Loss.

    2. This EVM is providing insertion…
