40-740-xx1 is a range of bi-directional RF multiplexers with
bandwidth beyond 2000 MHz.
They are configured as single 8:1, dual 4:1 or single 4:1, all
with excellent insertion loss, VSWR and isolation. 50 Ω and
75 Ω versions are available with a wide choice of connectors:
• 40-740 Single 4 to 1 RF Multiplexer with automatic
termination of all non-selected signals.
• 40-745 Single 8 to 1 or 4 to 1 RF Multiplexer
(no termination option).
• 40-746 Dual 4 to 1 RF Multiplexer
(no termination option).
Applications for the 40-740-xx1 include routing high
frequency signals to and from oscilloscopes, analyzers,
signal generators and synthesizers, telecoms tributary
switching (from 2 MBit/s to 155 MBit/s), video/audio
switching and switching high frequency logic signals.
