we plan to use adl5380 in a Rx direct conversion archirecture.
LO freq=1GHz, LO synthesizer ADF4360-2 in RF/2 operation mode.
We'd like to use a direct adf4360-2 output--->ADL5380 differential connection in order to ommit balun.
Would ADF4360 Pout sufficient?
Is there a suggestion regarding differential low pass filter design to suppress 3rd order harmonics?
Should I consider with higher order harmonins as well?
Should the low pass filter be deigned for 100Ω input and 50Ω output impedances?
The adl5380 data sheet specifies a LO pwr range of -6dbm to +6dbm . I assume that this applies to the usuage of a balun to supply LO single-ended.Correct?
How the LO input pwr requirements applies to the differential feeding scheme?
Thank you in advance,
