Hi, I am using HMC1049LP5E. The RF input is DC coupled. What is the  maximum DC bias  voltage can I apply to the FR input pin. Can I use ACG3, ACS2 pins to DC bias HMC1049?

  • Hi,

    YOu need to use a DC block capacitor to AC couple the RF input pin. Applying voltage through RF input is not recommended.

    For the RF output you need to use a `bias tee` to apply Vdd.

    ACG pins are for low frequency termination, no bias voltage is suggested to be applied through those pins.
