The 40-881A-004 is a quad 50Ohm 4 to 1 RF multiplexer with 8GHZ bandwidth.The 40-881A range of multiplexers have automatic termination of unused signals and are available as a single MUX in one PXI slot, a dual MUX in two PXI slots, or triple and quad MUXs in three slot PXI modules. This PXI multiplexer exhibits low VSWR characteristically over the full operating frequency range and consistent insertion loss characteristics. The use of solid state switches ensures a long service life with no wear out mechanism, making the 40-882 MUX ideal for ATE systems requiring frequent and fast operating RF switching.
