High performance RF multiplexer module suitable for switching microwave signals to 18 GHz with remotely mounted relays, failsafe version.
Estimated shipping is 20 to 40 working days
Please contact sales office for availability
The 40-785C-422-E (PXI) and 42-785C-422-E (PXIe) are dual failsafe SP4T 18 GHz unterminated microwave multiplexers with remotely mounted relays. The 40/42-785C range of multiplexers are available in single or dual, SP6T or SP4T configurations with relays mounted on the front panel. Remote versions are also available which can support up to three multiplexers in a single slot.
Remote versions occupy less PXI panel space and allow the microwave relays to be placed closer to the UUT and other RF test equipment. This can shorten the length of RF cable runs and improve system performance. Remote multiplexers are supplied complete with a 1.5 m interface cable.
The 4x-785C modules are suitable for constructing complex microwave switching networks and provide a range of configurations to suit most applications. They offer high performance with application mainly in the microwave region, however there are many uses in the RF spectrum where extremely low insertion loss and ultra-high isolation are critical. Connection is by high performance SMA, SMA-2.9, SMA-2.4, SMA-1.8 or N-type connectors for 50 Ω versions.
Relay Cycle Counting
To aid with module “health” monitoring all versions are provided with a relay cycle counting cycle feature. The number of operations per contact are stored on the module and can be used to determine if a relay is approaching EOL. This information could allow system connections to be revised so that signals applied to heavily used contacts are swapped with lightly used contacts to prolong the working life of the relay(s).
To provide maximum flexibility this range is available with either failsafe or latching relays. The contacts of failsafe relays return to the default state when system power is removed whereas latching relay contacts retain their last set state when the power is removed.
