National Instruments 782576-01 PXI RF Multiplexer Switch Module

The part number 782576-01 from National Instruments is the identifying part number for the PXIe-2790 PXI RF Multiplexer Switch Module. This module supports signals with a minimum input frequency of 10 MHz and a maximum input frequency of 6 GHz. The module has a Characteristic Impedance of 50 Ω nominal because matching the impedance of the module with the transmission line or other components in the system is crucial for minimizing signal reflections and maximizing power transfer. The module is designed to couple AC signals needed for signal transmission and reception. 

The output trigger signals of the 782576-01 RF module can be routed to trigger lines 0 through 7. These trigger lines in a module are used for system synchronization and system coordination when connected with other modules. The Pulse width of the trigger is programmable between 1 ms to 62 ms allowing it to be used in various applications. To power the module 0.9 W at 3.3 V, 0.6 W at 12 V is required.

The 782576-01 RF Module features FET switches which are high-frequency performance and have low insertion loss. The front panel of this module has 7 SMA jacks, and female (I/O) connectors which serve as input/output ports for interfacing with external devices or systems. The RF module is designed as a single-slot 3U (3 unit) module compatible with PXI (PCI eXtensions for Instrumentation) or cPCI (CompactPCI) systems. Its dimensions are 21.6 cm (8.5 inches) in length, 2.0 cm (0.8 inches) in width, and 13.0 cm (5.1 inches) in height. It weighs approximately 394 g (13.9 oz).

To operate the RF module it is recommended by the manufacturer to use it in an environment with an ambient temperature between 0 °C to 55 °C and can also be stored in an environment with a temperature of -20 °C to 70 °C. The relative humidity rating of this module is 5% to 85%, non-condensing, keeping the humidity between this range prevents moisture build-up inside the module. With a Pollution degree level of 2 this module is suitable for environments with low to moderate levels of contamination.
