The part number 778572-97 from National Instruments is the identifying part number for the PXI-2597 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 supports Single-Pole Double-Throw relay configurations, has a maximum switching voltage of 90 Vrms and a maximum carry current of 1.73 Arms per channel, and can handle a maximum RF carry power of 150 Watts for frequencies up to 3 GHz.
778572-97 is designed to have insertion loss of less than 0.2 dB for frequencies up to 3 GHz, less than 0.3 dB up to 8 GHz, less than 0.4 dB up to 12.4 GHz, less than 0.5 dB up to 18 GHz, and less than 0.7 dB up to 26.5 GHz. To minimize crosstalk during switching between the channels, it provides channel-to-channel isolation which is greater than 80 dB up to 3 GHz, greater than 70 dB up to 8 GHz, greater than 60 dB up to 12.4 GHz, greater than 60 dB up to 18 GHz, and greater than 55 dB up to 26.5 GHz. This RF module has a quick relay response time with an Operating time of 15 ms and a release time of 15 ms.
The module is enclosed in a 3U PXI/cPCI form factor and requires three slots in a PXI chassis. The dimensions are 21.6 cm × 6.1 cm × 13.0 cm (8.5 in. × 2.4 in. × 5.1 in.), and the product weighs 490 g (17.3 oz). It requires 3.3 Volts DC at 2.5 Watts, 5 Volts DC at 1 Watt, and 12 Volts DC at 3 Watts from the PXI backplane to operate.
778572-97 operates within an ambient temperature range of 0 degrees Celsius to 55 degrees Celsius and supports relative humidity levels from 10% to 90%, non-condensing. In addition, it can withstand storage temperatures from -40 degrees Celsius to 70 degrees Celsius and storage humidity levels from 5% to 95%, non-condensing. It is designed to be mounted at a maximum altitude of 2,000 meters and meets Pollution Degree 2 standards.
