Agilent N2268A
• Ideal for wireless
communication test
• Insertion loss
<1.7 dB at 3.5 GHz
The N2268A multiplexer module
has two 1x4 independent multi-
plexers with SMA connectors,
delivering high performance,
very low insertion loss, high
isolation, and excellent VSWR
performance. This high-density
RF multiplexer module is an
economical RF signal switching
solution. Its 3.5 GHz bandwidth
guarantees signals will not be
degraded when switched from
source to destination. Each group
of four channels is isolated from
the other and from the chassis to
prevent ground loops. The wide-
bandwidth performance enables
quality dynamic-range RF signal
measurements using oscilloscopes,
spectrum analyzers, network
analyzers, and GSM/CDMA test
sets. Typical test applications
include switching signals of
Bluetooth transceivers and
L1/L2 GPS receivers, 1.8/1.9 GHz
wireless communication devices
(such as GSM, CDMA, 3G,
DCS1800, and PCS1900 base
stations), and mobile phones.
It can be also used to route
satellite signals.
