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
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: What is the BW(30dB)-outband bandwidth? Posted:
Wed Jun 08, 2005 2:41 pm
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
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
