Melbourne Satellites - C-band Band Pass Interference Filters

C-Band

INTERFERENCE FILTERS

The Model 7893D C-band bandpass filter is installed between the feedhorn and the LNB (or LNA) to suppress strong out-of-band interference.

FL-7893D

Features:

Less than 6 inches long
Low Differential Group Delay
Low Insertion Loss
Highly Selective
Also rejects transmit band (5.8 - 6.5) GHz - eliminating the need for a separate TX reject filter.
