    Thread Summary
    
                The user needs to set a 10 dB attenuation using the HMC1122LP4ME in parallel mode. The solution is to engage the 2 dB and 10 dB attenuators (D2 and D4 low) while bypassing the others (D0, D1, D3, D5 high).

    Hello,
    I have Question to set 10 dB Attenuator in HMC1122LP4ME parallel mode, in datasheet HMC1122 (Rev. B) page 10 after 8 dB state jump to 16 dB state. I actually need 10 dB attenuator.
    Thanks before
