The 40-878-221 (PXI) and 42-878-221 (PXIe) is a dual 50 Ω 4 to 1 RF multiplexer with SMB connectors in a single PXI or PXIe slot. It is also available in single or quad configurations.
The module is based on the latest micro-electromechanical system (MEMS) switching technology and has low insertion loss and VSWR. In addition, MEMS devices have a long operational life of >3 billion operations and benefit from an operating time of <20 μs allowing greater test system throughput. The multiplexers have excellent and repeatable RF characteristics beyond 4 GHz with each path having a nominally equal insertion loss. The 4x-878 minimizes the injection of noise and unwanted signals into the signal path by careful attention to the mechanical and electrical design.
Versions with MCX or SMB connectors are available, allowing users to simplify cabling issues by matching them to other connectors in their test system.
