Agilent 34905A 50Ω
Agilent 34906A 75Ω
Dual 4-channel RF Multiplexers
• 2 GHz bandwidth
• BNC to SMB adapter
cables included
The 34905A and 34906A RF multi-
plexers offer broadband switching
capabilities for high-frequency and
pulsed signals. Use them to route test
signals between your device under
test and your signal generator, oscil-
loscope, spectrum analyzer, or other
instrumentation.
The RF multiplexers are arranged as
two independent 1x4 multiplexers,
each with a common shield and a
switched center conductor.
Connections can be made directly to
SMB inputs with 2 GHz usable band-
width, or to the BNC-to-SMB
adapters provided with 1 GHz band-
width. Multiple banks may be cascad-
ed together for applications requiring
even larger topologies—create a stub-
less 16:1 multiplexer in a single
frame.
