Agilent 44476A
• Switching signals from
DC to 18 GHz
• Triple 1-to-2 microwave
multiplexers
The 44476A includes three
independent SPDT 50 Ω coaxial
relays with excellent electrical
performance from DC to 18 GHz.
For general-purpose microwave
switching applications, the
module can be used to switch
separate signal sources for a
multi-band receiver/transmitter
testing application. The 3 mm
SMA connector on the module
edge simplifies wiring.

Agilent 44476B
• Supporting varieties of
microwave coaxial relays
• Two set mounting holes for
coaxial relays
The 44476B brings multi-port
50/75 Ω coaxial switching
flexibility to your test system.
It has two set mounting panels,
so any two Agilent 876XX
coaxial switches can be mounted.
The coaxial switches come in
three-, four-, and five-port
configurations. This flexibility
allows you to use the different
switches for a variety of
applications, constructing
transfer switches, switch
matrices and more. Using the
876XX in conjunction with the
44476B allows you to extend
your automated three-port
switching to 26.5 GHz. Coaxial
relays must be ordered separately
when using with this module.
The coaxial switches that can be
used are listed below. Option 011
designates the switches for a
coil voltage of 5 VDC.
