Structure of LOW-PASS filter in particular for DVBT-DVBH

摘要

A structure of a LOW-PASS filter, in particular for DVBT-DVBH, comprining a first STOP BAND filter with narrow band with insertion loss of <1.5dB across the transmitted band, an insertion loss at 790MHZ or 702MHz of <8dB, and an insertion loss at 739MHz or at 705MHz of >30dB followed by a second filter, in cascade, that can increase the insertion loss from 790 to 793MHz.
