SX1115
RF Head with
SF1119/SF1120 Duplexers
5.8 GHz U-NII RF Outdoor Units
Compatible with Cisco Systems
uBR7246/7223
Point-to-Point Router
The SX1115 is compatible with Cisco’s WT2700 Wireless
Technology Suite for operation in the 5.8 GHz U-NII
(Unlicensed National Information Infrastructure) band.
The RF Head (referred to as an outdoor unit or ODU)
interfaces between the uBR7246/7223 router and
antenna. The Tx and Rx signals sent between the router
and ODU operate at IF frequencies that are combined
onto a single IF cable using frequency division duplexing
(FDD) along with the 24 MHz reference signal and DC
bias. The ODU then provides the conversions necessary
to operate in the U-NII band.
The RF Head is fully compatible with Cisco’s VOFDM
(Vector Orthogonal Frequency Division Multiplex)
modulation format and complies with CSA/FCC
requirements. Duplexers are available to operate in two
different subbands. The Tx/Rx frequencies may be
interchanged in the field by reversing the duplexer
connections.
A control cable also connects between the router and
ODU and is used to configure and monitor status of
the ODU. Tx power and Rx gain can also be adjusted
in real time.
