Description
700 RHM
[Down Link]
This module filters 700 DL RF signal from link antenna, amplifies with
low noise, filters A/B/C/UpperC sub-band signals by digital band pass
filters and transmits the selected 700 DL RF signal to optical module.
[Up Link]
This module filters 700 UL RF signal from optical module, filterers
A/B/C/UpperC sub-band signals by digital band pass filters, amplifies to
get high power and transmits 700 UL RF signal via antenna port.
850 RHM
[Down Link]
This module filters 850 DL RF signal coming from link antenna,
amplifies with low noise, filters sub-band by digital band pass filters
and transmits the selected 850 DL RF signal to optical module.
[Up Link]
This module filters 850 UL RF signal coming from optical module, filters
sub-band by digital band pass filters, amplifies to get high power and
transmits 850 UL RF signal to antenna.
1900 RHM
[Down Link]
This module filters 1900 DL RF signal coming from link antenna,
amplifies with low noise, filters sub-band by digital band pass filters
and transmits the selected 1900 DL RF signal to optical module.
[Up Link]
This module filters 1900 UL RF signal coming from optical module,
filters sub-band by digital band pass filters, amplifies to get high power
and transmits 1900 UL RF signal to antenna.
2100 RHM
[Down Link]
This module filters 2100MHz DL RF signal coming from link antenna,
amplifies with low noise, filters sub-band by digital band pass filters
and transmits the selected 2100MHz DL RF signal to optical module.
[Up Link]
This module filters 1700 UL RF signal coming from optical module,
filters sub-band by digital band pass filters, amplifies to get high power
and transmits 1700 UL RF signal to antenna.
GPS FEM
This unit filters GPS L1 band signal, amplifies by low noise, converts
GPS signal into optical signal and transmits this optic signal to RU site
via fiber. This unit has two GPS ports to support GPS redundancy
function. If one GPS fails, second GPS port switch over automatically.
RHOM
[Down Link]
This module combines 4-band mobile RF signal from 700/850/1900/
AWS RHM or GPS-FEM and converts into optical signal and transmits to
RU site via fiber.
[Up Link]
This module converts optical signal coming from fiber into RF UL signals
and amplifies UL signals to compensate fiber loss and transmits to
700/850/1900/AWS RHM or GPS-FEM.
