HMC1056LP4BE - LO Port Attenuator

Question asked by david_d on Jun 1, 2017

Is a 3dB attenuator required/recommended at the LO port of this IQ mixer?  The incoming transmission line in my design is matched to 50 ohm.  It looks like many of the IQ evaluation boards from Analog Devices dispense with a 3dB pad on the LO.

 

Many Thanks,

 

David
