Oh, pics here.
Hi all.Here attached pics of UmSELv1 inputs leakage for E-GSM900.Measured at MIXER inputs, i.e. it is diversity switchesšisolationšand/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.2013/3/18 Alexander Chemeris <alexander.chemeris@gmail.com>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:
