AD9371 ORX Balun B0322J5050AHF mismatch with the DS

Hello ,

The UG-992 Matching section and the Design file package of the AD9371 shows that ORX Balun B0322J5050AHF pin 5 should be connected to the GND. in Anaren DS it shows to put it under Do not connect.

Also, this Balun is part of a matching network for 1800-2800MHz while in the Datasheet of Anaren it says that the Balun should work up to 2200MHz

Please advise what to do and why.

    The UG-992 Matching section and the Design file package of the AD9371 shows that ORX Balun B0322J5050AHF pin 5 should be connected to the GND. in Anaren DS it shows to put it under Do not connect.

    Connecting the pin 5 of  B0322J5050AHF is not harmful as long as there is no DC present. You can leave it open as per the datasheet recommendation.

    Also, this Balun is part of a matching network for 1800-2800MHz while in the Datasheet of Anaren it says that the Balun should work up to 2200MHz

    We didn't find any issue using it above 2800 MHz as the performance of balun meets the EVB requirements. 

    Please find the wideband performance graph from the datasheet of B0322J5050AHF.
