ALGA C-Band 5G "Blue" Filter,
4.0-4.2 GHz- FLT-VSF-K-01-03
Microwaves specialized filter prevents
interference from 5G base stations that are
in the proximity of C-Band satellite systems.
The filter design has been specifically
approved by the C-Band Alliance.
C-Band (3.8-4.2 GHz) is used for satellite
services, radar, and microwave links. With
the introduction of 5G networks, these C-Band
frequencies will now be shared with a wider
range of services. The resulting interference
signals can be powerful enough to saturate
the sensitive C-Band satellite receiving
systems which may result in total loss of
solve this problem, Alga has designed a
filter that will clear portions of the C-Band
spectrum to support the growth of mobile data
and the introduction of 5G services in the
USA and around the world.
Alga Microwave FLT-VSF-K-01-03 is for
use to mitigate disruption and interference
of existing services due to the reallocation
of the spectrum to 5G transmissions.
