Category: Datasheet/Specs
Product Number: adrv9005
The ADRV9001 System Development User Guide states that "When selecting a balun/transformer for the receive paths, use a 2:1 impedance transformation to accommodate the 50 Ω single-ended
impedance to 100 Ω differential impedance, as required by the ADRV9001 receiver inputs" (page 267).
However, looking at the Jupiter-SDR schematic, the ADRV9002 Rx paths are using TCM1-83X+ which have 1:1 impedance transformation baluns (per datasheet, page 15).
Why did they used 1:1 balun when 2:1 is needed, and which Balun Impedance Transformation Ratings should I use with ADRV9005 (both Rx and Tx)?
