The 40-881A-001 is a single 6 to 1 50Ω RF multiplexer with 8GHz bandwidth and automatic termination of unused signal channels. It is available as a single or dual MUX in one and two PXI slots respectively.

The 40-881A exhibits low VSWR characteristic over the full operating frequency range and consistent insertion loss characteristics. The use of solid state switches ensure a long service life with no wear out mechanism, making the module ideal for ATE systems requiring frequent and fast operating RF switching with no contact bounce.

Note: A last time buy date of 1st December 2022 has been set for this product due to component obsolescence after which it will no longer be possible to place further orders. After the last time buy date passes service and support will continue to be offered on a best effort basis.

For new system designs, please refer to the 40-881B-001 which is available with a PXI or PXIe interface.
