Data Sheet

The National Instruments PXI-2545 is a 4x1 high-frequency terminated multiplexer switch module suited for routing signals from DC to 2.7 GHz in 50 Ω RF applications. It can switch up to 30 Vrms or 500 mA, with a maximum power rating of 10 W. The internal termination of the NI PXI-2545, which helps prevent high-power reflections that arise from open channels on the module, makes it ideal for use in RF applications where such reflections can damage the source. The module also provides users with excellent insertion loss, voltage standing-wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use the onboard relay count tracking feature to predict relay lifetime and reduce unexpected system downtime.

Note: The bandwidth specification of a switch module is not an absolute specification and is determined by vendor standards. Although you can route higher-frequency signals through this switch module, these signals may encounter more degradation than those at lower frequencies. To determine the best switch module for your application, review the insertion loss, VSWR, and isolation specifications of the product for the bandwidth of your application. For more information on choosing the right RF switch for your application, review “The Guide to Selecting an RF Switch” under the Resources tab.
