Hi all.
Here attached pics of UmSELv1 inputs leakage for E-GSM900. Measured at MIXER inputs, i.e. it is diversity switches isolation and/or between LNA's (PCB).
As for the DCS, my first quick test shows that isolation is not so good and around 15dB only.
Best regards, Andrey Sviyazov.

Hi all,
We've received UmSEL units from the manufacturing and working on its testing and integration right now. Results are as expected so far, which is a good sign.
Attached are pictures of UmSELs and UmSEL on a UmTRX:
