The Andrew Crossband Coupler
combines signals from wireless systems
operating in the 806–960 MHz bands
with signals from systems operating in
the 1710–2170 MHz bands onto a
common feeder cable.
These couplers use novel suspended
stripline printed circuit board technology
to provide extremely low insertion loss
and high power handling capability in a
compact rugged weatherproof housing.
Sealing gaskets provide protection from
moisture ingress at all interfaces.
The Andrew Crossband Coupler
641280 product family features
extremely low insertion loss (0.10 dB @
806–960 MHz and 0.15 dB @ 1710-
2170 MHz). A minimum 47 dB isola-
tion is provided between output ports
641280 Family of Indoor/Outdoor Diplexers for Dual-Band
Combining Signals of 806–960 MHz and
1710–2170 MHz

One Company. A World of Solutions.
Crossband Coupler
These couplers feature precision 7-16
DIN female connectors and an external
grounding stud for lightning protection
purposes. A mounting bracket
and two band clamps are provided for
quick deployment and installation. These
units are stackable and do not require
additional spacer hardware.
This product family is also available
in different dc block and dc bypass
versions. This feature allows full
compatibility with systems requiring
tower mount amplifiers. The internal dc
block design provides lower insertion
loss and better reliability than dc block
designs that contain ceramic dc blocking
capacitors.
