Lime SDR-USB v1.4s: Detached TX2_2 RF Transformer, Assessing Reusability

Hello,

The TX2_2 RF transformer on my LimeSDR-USB v1.4s board has detached.

The PCB pads are intact. Based on my inspection, the detached component is a Mini-Circuits TCM1-63AX+.

Since this is a wire-wound component with naturally exposed coils, I want to verify if the bottom terminal pads or internal micro-wire connections typically get compromised when detached like this.

Questions:

  1. Is it viable/safe to re-solder this specific detached unit, or is the risk of internal damage and RF performance degradation too high?

  2. If replacing it is necessary, are there specific rework precautions or suitable equivalent parts for the TCM1-63AX+?

Thanks for any technical input.

Regards, Uhar.
