Hi,

 

We plan to use ADF4360-2 to supply a 1GHz LO to ADL5380 in a direct Rx converion architecture.

I would appreciate it if you provide me with the following information:

a. typ/wc harmonics contect for Rf/2 option

b. Which is the differential RF output impedance?

c. Is there any suggestion regarding differential interfacing (matching & low pass filtering circuit) with ADL5380 LO inputs?

d. Should a differential low pass filter with Zin =100Ω and Ζout=50Ω be designed?

e. Which is estimated ADF4360-2 output pwr for RF/2 in differential interfacing?

f. Which is estimated ADF4360-2 output pwr for RF/2 in single endedl interfacing?

 

Thank you in advance
