What is the BW(30dB)-outband bandwidth? - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

I am designing a BPF for the 3G transceiver.
For the transmitter, the BPF is operating from 1920MHz to 1980MHz and it has 30dB outband rejection and 2.5dB in-band insertion loss.
The BW(3dB)- passband bandwidth is 60MHz and
What is the BW(30dB)-outband bandwidth???
Pls help me if anyone know this, thank you!!

30dB attenuation for the closest next system (it means 1990MHz in some countries unfortunatelly) pls check FCC, ETSI and Japanese frequency allocation
