Wed Jun 08, 2005 2:41 pm Dear all,
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!!

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