Description
The National Instruments PXI-2547 PXI RF Multiplexer Switch Module is a versatile and high-performance component designed for use in PXI systems. The product, bearing the part number 195869M-01L (778572-47), falls under the category of PXI Switches. It is characterized by its unique model number PXI-2547 and is engineered to facilitate efficient signal management within complex systems.
This module is notable for its 8×1 and SP8T topology, enabling it to support a wide range of signal routing configurations. It operates effectively within a frequency range from DC to 2.7 GHz, making it suitable for a broad spectrum of RF applications. The device ensures signal integrity through its 50 Ω impedance, and it is capable of handling a maximum switching current of 0.5 A per channel and a maximum switching voltage of 30 V.
One of the key performance metrics of the PXI-2547 is its insertion loss, which is less than 1.05 dB (typically <0.7 dB) at frequencies ≤1 GHz, and less than 2.0 dB (typically <1.6 dB) at frequencies ≤2.7 GHz. This ensures minimal signal degradation through the switch. Additionally, it boasts a low DC path resistance of <0.25 Ω initially, rising to ≥1.0 Ω at the end of its life cycle, further contributing to its effective performance.
The module is equipped with 9 SMA jacks (gold plated) for connectivity, ensuring robust and reliable connections. Its dimensions are 8.5 in. × 0.8 in. × 5.1 in., and it weighs 9 oz., making it a compact yet sturdy component suitable for integration into a variety of PXI systems. The device utilizes an electromechanical, latching relay for its
