National Instruments PXIe-2544 RF Multiplexer Switch Module with 8x1 Terminal Multiplexer 6.6 GHz RF Signal and 50 Ohm Impedance

The National Instruments PXIe-2544 (Part Number: 780587-44) is a high-performance PXI RF Multiplexer Switch Module featuring 8x1 terminal multiplexing technology. Designed for precision RF applications, this module delivers reliable switching performance with excellent signal integrity.

• 8x1 terminal multiplexing configuration for flexible signal routing
• Operates with input frequencies from 10 MHz minimum
• 50 Ω characteristic impedance (Z0) for optimal signal transmission
• Supports RF signals up to 6.6 GHz with low insertion loss
• AC coupling capability for enhanced signal processing
• High-performance solid-state relays for fast switching (122 μs maximum)
• Front-panel SMA connectors for convenient RF device connection
• Compact design: 8.5" x 0.8" x 5.1" (LxWxH), 538g weight

The PXIe-2544 features excellent power handling capabilities with maximum safe continuous RF power of +30 dBm when chassis power is on (+20 dBm when off). The module maintains low insertion loss across frequency ranges, with a thermal coefficient (α) of 3,402 ppm/°C for stable performance in varying temperature conditions.

The module supports a maximum DC input voltage of ±8 V. Always ensure proper power sequencing and observe all specified voltage limits for safe operation.
