A new set of PXI RF switches supports up to 10 off SP4T RF switches in a single module and is available in two different versions based on a common switch design. The 40-755 multiplexer modules from Pickering Interfaces come in two versions. The high-density version occupies just one slot of a 3U PXI chassis and uses a high-density multi-way connector that is suitable for switching frequencies to 500 MHz. The higher frequency version uses SMB connectors and is suited for switching signals to 1.8 GHz.

The 40-755 is the highest density SP4T switch available in the standard PXI format and is suitable for use in both commercial and military ATE systems. It is a suitable replacement for use in older VXI-based military ATE applications that are being replaced and/or upgraded by PXI/LXI solutions where great numbers of SP4T are used as standard RF switch sub-assemblies. The two models use a switch design based around high-quality electromechanical relays, and in addition to being supported in any PXI-compliant chassis, they can be supported in Pickering Interfaces Modular LXI Chassis.
