PXI-2590

National Instruments PXI-2590 / PXI-2591 4x1 High-Frequency Unterminated Multiplexing Switches
Features

• High-Bandwidth Electromechanical Relays
• 50 Ω Characteristic Impedance
• Excellent Insertion loss

The National Instruments PXI-2590 / PXI-2591 4x1 High-Frequency Unterminated Multiplexing Switches are capable of switching signals from DC to 1.3 GHz (PXI-2590) and DC to 4 GHz (PXI-2591). The characteristic impedance of the channels is 50. For the PXI-2590, the maximum voltage rating of the switches is 24 Vrms with a maximum current of 1 A. For the PXI-2591, the maximum voltage rating is 30 Vrms with a maximum current of 330 mA. All are well suited for applications that require the routing of high-frequency signals inside automated test equipment (ATE) systems because they can switch signals with a very low insertion loss. In addition, the excellent voltage standing-wave ratio (VSWR) and isolation parameters make these modules the perfect choice in a system geared to high-frequency applications.
