Description
The part number 778572-47 represents a high-quality PXI Switch, specifically the model PXI-2547. This device is designed as a 2.7 GHz 50 Ohm 8X1 Multiplexer, making it suitable for a wide range of applications that require high-frequency switching capabilities. It operates within a frequency range from DC to 2.7 GHz, ensuring versatility in its use.
The topology of this multiplexer is an 8×1 configuration, indicating that it can connect one output to any of its eight inputs. It has an impedance of 50 Ω, which is standard for RF applications, ensuring minimal signal reflection and loss. The maximum switching current per channel is rated at 0.5 A, and it can handle a maximum switching voltage of 30 V, providing a balance between performance and power handling capability.
When it comes to performance metrics, the insertion loss at ≤1 GHz is less than 1.05 dB, with a typical value being even lower at less than 0.7 dB. For higher frequencies up to 2.7 GHz, the insertion loss remains below 2.0 dB, with typical values being less than 1.6 dB. Such low insertion loss figures are indicative of the switch’s efficiency and the high quality of signal transmission it provides.
The device features gold-plated 9 SMA jacks for its connectors, ensuring excellent conductivity and corrosion resistance, which is crucial for maintaining signal integrity over time. The physical dimensions of the PXI-2547 are 8.5 in. × 0.8 in. × 5.1 in., and it weighs 9 oz., making it compact and easily integrable into various setups without taking up excessive space.
Regarding durability, the initial DC path resistance is below 0.25 Ω
