HMC560 DC Block

Question asked by mattcarter on Mar 26, 2015

The HMC560 mixer datasheet indicates that the IF port is DC coupled and that a DC block should be used if response to DC is not required.   The datasheet also indicates that the RF and LO ports are DC coupled and matched to 50 ohms but has no indication that a DC block is required.  In my application the RF and LO ports will have a DC path to ground via an attenuator pad but there will be no DC present.  Does anyone know if a DC block would be necessary in this application?
