B0322J5050AHF for AD9371's TX port

gbk on Nov 29, 2023

Thread Summary

The user asked if connecting 1.8V to Pin 2 of the Anaren B0322J5050AHF, which is labeled as GND, is an error. The final answer confirmed it is an error and suggested feeding 1.8V through Pin 3 or 4 instead. The accompanying answer provided a schematic and explained that Pin 2 is not used for DC feed in this configuration.

On page 252 in Fig. 150 it is shown that I can connect Pin 2 of Anaren B0322J5050AHF to the 1.8 V feeding line. However, in Anaren B0322J5050AHF datasheet Pin 2 is stated as GND. Is this an error? and how can i connect 1.8V in a right way to feed the AD9371's TX port . should i connect 1.8V to pin 2, or to pin 3,4?

Here L305 is a DNI component . The 1.8 V connected to pin2 can be used in transformer component but that isn't used here for DC feed . Attached the schematic below.The 1.8V can be fed through pin 3,4 as shown in the schematic.

S parameter files are available as part of the design file package, you can use the same for matching your eval board and then try evaluating .

Download the S Parameters from the below link:

Check UG 992 (Page 236) for more details on SEDZ models .
