Hi Alexander,

As far as I understand, the IF frequency should be 360 MHz as the UmSEL uses the TB0130A IF SAW filter. Its center frequency is 360 MHz.

Ok, thanks.

By the way, why do you say it would be a problem if IF was above 380 MHz ? Because of interferences ? In this case, would it still be problem if we install the UmTRX + UmSEL boards inside an enclosure ?

Well, the original question was from Harald, but the concern was with interference, yes.

I think it depends on the type of enclosure we use. Andrey should be able to comment here.
