The 40-754 single-pole, double-throw switch module from Pickering Interfaces is a PXI RF unit that supports up to 17 switches in a single module. It comes in two versions: a high-density device that occupies one slot of a 3U PXI chassis and uses a high-density MS-M RF multi-way connector for switching frequencies up to 500 MHz. A higher-frequency version is two slots wide, uses SMB connectors, and is suitable for switching signals to 1.2 GHz. The device is said to be the highest-density SPDT switch available in the standard PXI format and is suitable for use in automatic test equipment (ATE) systems. It can replace older VXI-based ATE applications that are being replaced and/or upgraded by PXI/LXI solutions, where great numbers of SPDT are used as standard RF switch subassemblies.
