National Instruments 778572-47 PXI RF Multiplexer Switch Module

The part number 778572-47 from National Instruments is the identifying part number for the PXI-2547 PXI RF Multiplexer Switch Module. This module is designed for signal routing in automated test systems and operates across a frequency range from DC to 26.5 GHz. This RF module has a maximum switching voltage of 30 V and a maximum carry current of 0.5 A per channel, and can handle a maximum RF carry power of 10 Watts. 

The module is designed to have insertion loss of less than 1.05 dB up to 1 GHz and less than 2.0 dB up to 2.7 GHz. The VSWR is maintained below 1.4 up to 1 GHz and below 1.6 up to 2.7 GHz, reducing signal interruptions and helps in impedance matching.  This RF module supports input trigger from PXI trigger lines <0...7> with a minimum pulse width of 150 ns and output trigger from PXI trigger lines <0...7> with a pulse width of 1 µs to 62 µs. The 778572-47 module have an expected mechanical life of 1 × 10^6 cycles and an electrical life ranging from 3 × 10^5 cycles at maximum load, ensuring long-term reliability.

The module is enclosed in a 3U, one slot, PXI/cPCI module form factor and requires one slot in a PXI chassis. The module dimensions are 21.6 cm × 2.0 cm × 13.0 cm(8.5 in. × 0.8 in. × 5.1 in.), and it weighs 255 g. This module is designed to operate at operational shock of 30 g peak, half-sine, 11 ms pulse with random operating vibrations of 5 Hz to 500 Hz, 0.31 grms. 

It operates within an ambient temperature range of 0 degrees Celsius to 55 degrees Celsius (Tested in accordance with IEC 60068-2-1 and IEC 60068-2-2.) and supports relative humidity levels from 10% to 90%, non-condensing g (Tested in accordance with IEC 60068-2-56.). The module can withstand storage temperatures from -40 degrees Celsius to 70 degrees Celsius and storage humidity levels from 5% to 95%, non-condensing. This module is designed to be mounted at a maximum altitude of 2,000 meters and meets Pollution Degree 2 standards.
