National Instruments Corporation 778572-56 NI PXI-2556 2.5 GHz 75 Ohm Dual 4X1 Multiplexer

The National Instruments PXI-2556 is a dual 4x1 high-frequency multiplexer switch module suited for routing signals from DC to 2.5 GHz in 75 RF applications. It can switch up to 30 Vrms or 500 mA, at a maximum power rating of 10 W. The multi-bank architecture of the NI PXI-2556 makes it ideal for test systems that require parallel operations such as the stimulus/response testing of video RF devices such as tuners. The module also features excellent insertion loss, voltage standing-wave ratio (VSWR), and isolation parameters to minimize signal degradation; its onboard relay-count-tracking feature can be used to predict relay lifetime and reduce unexpected system downtime.

Note: The bandwidth specification of a switch module, which is not an absolute specification, is determined by vendor standards. Although higher frequency signals can be routed through this switch module, they will encounter more degradation than those at lower frequencies. In order 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.
