• HMC424ALP3E Attenuation Response

    I am testing the attenuation response of the HMC424ALP3E and am getting unexpected results past 16dB attenuation. My input signal is at 6.5GHz and the below graph details the response I get as the attenuation is changed from 0dB to 31.5dB. It seems that…

  • HMC424ALP3E input power requirements

     

    I would like to know whether the digital attenuator HMC424ALP3E requires a linear power input or works fine with a switching power input?

    What is the best power input for HMC424ALP3E ?

    Thanks in advance!

  • Attenuation Accuracy of HMC424ALP3E

    Hi,

    I've question anout a spec of  Attemuation Accurasy in the datasheet of HMC424ALP3E. According to the datasheet, it is shown +/- (0.3 + 5% of Atten. Setting) Max dB.  What is 5%? Is it for dB or true value of attenuation?

    Best regards,

  • HMC424ALP3E : Signal level fluctuation after changing ATT

    Hello,

    We can see a level fluctuation of output signal after changing ATT on HMC424ALP3E.Could you please look at following pictures. They are in case of ATT 0dB to 16dB and 16dB to 0dB. Almost same situation as for other ATTs.
