Dual 4-channel RF Multiplexers
• 2 GHz bandwidth
• BNC to SMB adapter
cables included
The HP 34905A and HP 34906A RF
multiplexers offer broadband
switching capabilities for highfrequency and pulsed signals. Use
them to route test signals between
your device under test and your
signal generator, oscilloscope,
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 bandwidth, or to the
BNC-to-SMB adapters
provided with 1 GHz bandwidth.
Multiple banks may be cascaded
together for applications requiring
even larger topologies—create a
stubless 16:1 multiplexer in a single
frame.
